Streets of Rogue

UPDATE:
As pointed by EarthboundX in the comments, credit goes to Tleno for his amazing Steam guide!

This is the hardest way to get the hat, I unlock this achievement with the cop.

You are better off starting at the very beginning, even if you ace every floor you won't have sufficient votes if you start in Park or later levels.

Once you get to the Mayor's level, go to the gold building and talk to the clerk at the desk to initiate the voting process.

If you display your current level stats, you'll see indicators showing your total and current level support. Total support starts at negative, and changes at the end of the level. If there are more people who hate you than like you, it decreases by one, if more than like you, it increases by one. Having it at zero leads to no change. You have to make sure your total support is at least at +1 by the time you reach the mayor village.

Everyone hostile, annoyed at, or with a class that automatically hates you (like, crepes always hate blahds, scientists always hate gorillas) don't decrease the vote if they don't encounter you, but killing them increases your support on the floor. Every single character that is aligned, loyal, or friendly to you counts as a positive vote.

Everyone aligned with you by default and of the same class is a secured vote so try to keep them safe.

Everyone you attack or annoy count as a negative vote, that's why it's best to kill them outright unless you already have the vote secured for the floor.

You can secure votes by giving food items or cigarettes to office workers, liberating lab and prison captives (although zombies will be hostile unless you're a zombie yourself), completing optional quests, bribing bouncers.

Using the perfume makes everyone like you and secures their vote unless they are attacked, which immediately makes the item super useful when going for legal takeover.

Playing as a comedian you can kill off everyone who doesn't like your jokes, and keeping those who liked them alive.

You can pay downtown or uptown mafia members to influence elections, increasing your total support by a few points, but this works only once.

As the other guides explain, you need to have more people on each level view you favourably rather than being annoyed or hostile. You can check your character sheet to see your score at any time, and finishing a level with a positive score will increase your city score by one. Your city score needs to be positive when you reach the final level for you to be able to win the election.

I just managed to do this using a custom character. I basically made them a hybrid of the hacker and bartender, with:
-Charismatic trait to start each level with everyone friendly.
-Tech Expert to get access to extra options on computers.
-Laptop as the special ability, to hack from a distance.
-Two points in Endurance, Speed and Melee.

I turned on a bunch of mutators to make things easier:
-Infinite ammo
-Infinite melee durability
-Neutral cannibals
-No disasters
-No limits
-No patrolling cops

I also turned off a lot of traits to give more chance of useful ones turning up at the end of levels. The most useful ones in my run were:
-Friend of the Common Folk, to make some people loyal, which is a step up from friendly and seems to be worth double electability points.
-Nimble Fingers, for faster hacking.
-Random Reverence, to make some people aligned which is the highest level of favour and seems to count for two points towards electability per person.
-Slippery Target, to make enemy bullets miss and increase chance of survival in a fight.
-Sneaky Fingers, so that filling the hacking bar doesn't alert people.

With the hacking ability you can clear a lot of missions from a distance without risking getting into a fight or making people hostile, which counts against your electability. My tactics included:
-Hack a computer and set off gas which would nearly kill anyone affected, making them easy to finish off.
-Hack a clone machine to get a random ally (who counts for +2 electability if they survive). Get them to fight for you if possible.
-Hack the sell-o-matic to increase sale prices and have tons of money. Buy any beer and food so that you can always heal, and upgrade traits at the green machine. Also hack the ATM for free money.
-On Floors 4 and 5, hack the alarm buttons so that you can summon super cops. They join you temporarily and you can order them to attack hard-to-reach targets. But I think you can only summon 3 per level.
-Free any prisoners as they become loyal and are worth more electability points.
-Hack TVs to lure enemies near before exploding then. And hack fridges which can be made to "run" which will break walls and can open easy routes past guards.
-Make sure there aren't cops around when hacking as this will aggro them. Also make sure no-one inside the building will see. If the hacking triggers an alarm they'll come looking, so make sure you have an escape route ready.

This all worked out pretty well for me. It was an easy run and I ended up with a positive electability on every single level.

Objective: Win the election
Requirements: Have Positive +1 or Higher (Green Font) Electability (City) status before talking to Clerk and Run for Mayor on Floor 6 Mayor Village
Checking Status: Pressing the double square button will bring up your Stats menu which shows both Electability values at any given time. At the floor completion screen it will also show this menu
Co-Op Note (Online Game): I attempted this with another player 3 separate times and each time if the host or the guest talked to Clerk neither player got the achievement to pop

Process
Each Floor you complete with Positive +1 or higher (Green Font) Electability (Floor) will increase your Electability (City) by +1
Each Floor you complete with Negative -1 or lower (Orange Font) Electability (Floor) will decrease your Electability (City) by -1
Each Floor you complete with Neutral Electability +0 (White Font) will neither increase or decrease your Electability (City)
You may increase Electability (City) +2 a single time by talking to a Mobster on any floor even Mayor Village:
- press and selecting option: Influence Mayoral Election - $280(this value varies) press

Electability (City) Start Values
Normal Game no Mutators: Electability (City) -5
- You must complete at least 6 floors with Positive +1 or Higher (Green Font) Electability (Floor) without paying the Mob
Quick Game Mutator: Electability (City) -3
- You must complete at least 4 floors with Positive +1 or Higher (Green Font) Electability (Floor) without paying the Mob

These values do not change based off using Elevator Access to higher Zones: Industrial, Park, Downtown, Uptown
- For the quickest run use Mutator: Quick Game and start on Uptown (5-1). You will play 2 floors before reaching Mayor's Village with a Electability (City) -1. Now (or on one of the previous floors) Pay the Mob and you will be at +1 and able to win the election

Contributors to increasing Electability (Floor)
Actions
Neutralizing Rivals: Rivals are automatic hostile NPC's to your current character (red circles around them)
Traits to make NPC's Rivals
- Blahd Basher: Blahds will attack on sight. Extra XP for killing Blahds. +1 Electability (Floor) for each kill
- Crepe Crusher: Crepes will attack on sight. Extra XP for killing Crepes. +1 Electability (Floor) for each kill
- Scientist Slayer: Scientists attack on sight. Extra XP for killing Scientists. +1 Electability (Floor) for each kill

Saving NPC's (Any Action that makes them aligned with you green circle)
- Rescue Slaves
- Rescue Apes
- Rescue non hostile (red circle) NPC's from jails
- Bribe Bouncers or anyone
- Enslave people
- Adding followers
- Have neutralize targets leave game (only possible with certain setups)
- Turning NPC's in to zombies (Trait: Zombiism, Special Ability: Zombie Phlegm (Followers))

Aligning people with you using Traits (Electability (Floor))
Friend of the Family: Mobsters are aligned with you (green circle)
Friend of the Common Folk: Generic denizens of the city are loyal to you. Aligns them (green circle)
No In-Fighting: Can't hit most people you are aligned with (Green Circle) and they can't hit you. The same goes for Loyal and submissive.
- This one is extremely useful if you are going the aligned submissive of follower traits playstyle, which you should be for this achievement though not required

Aligning traits have the potential to start you at each floor with Positive Electability (Floor), however the biggest contributor for this is the following trait:
Charismatic: Most people are initially Friendly toward you. Enter some private property without issue.
- PreBuilt Class Bartender has this trait so if you want to accomplish this achievement without using a custom character he is your guy

Using a custom character with the above traits I have seen Electability (Floor) start as high as +22 (average is around +10), nearly impossible for you to mess it up.

Now that the data is out of the way: Simply play through the floors, kill any rival(s) you see (if you have any) though most likely they will see you first and force a conflict. Save anyone that can be saved, Bribe whoever you can, Enslave whoever you must, turn everyone in to zombies if that's your thing, Cheat if you must by Paying the Mob and complete your missions to unlock the elevator and move on to the next floor as quickly as possible once you have Positive Electability (Floor).

Once you reach Floor 6 Mayor Village
Sometimes the bouncers may get aligned (green circle) with you if they do they will simply let you pass, otherwise leave weapons (you will not need them) or bribe them. If you kill them Robo-Cops will be released and you will have to avoid them; they will attack on sight no questions asked.
- If you are playing zombie you will need item: Translator to talk to the guards/clerk/mayor. Also wise to dismiss your followers so they don't create a apocalypses on this floor.

Once inside the front gate make your way to Clerk (inside the usually big gold/yellow building behind a desk).
Talk to Clerk press , select option: Run for Mayor press

He will then proceed to walk to the park and stop on the north eastern corner of the park to the right of the podium.
Talk to Clerk in park after Mayor arrives press, select option: Gimmie Those Results! press
Achievement will Pop

At this point you are free to do what you wish however if you wish to see the Legal Takeover speech talk to the mayor.
Talk to the Mayor press , select option: Gimmie My Hat! press
Interact with the podium press , select option: Speech! press


My Game/Character setup (used in both Xbox and Windows play through)
Mutators Used: Infinite Ammo, Money Rewards, Neutral Cannibals, No Cowards, No Disasters, No Patrolling Cops, Quick Game
Custom Character
Stats: Endurance: 3/4, Speed 1/4, Melee: 1/4, Firearms: 4/4
Traits: Friend of the Family, No In-Fighting, Blahd Basher, Crepe Crusher, Scientist Slayer, Loud, Charismatic, Poor Hand-Eye Coordination
Starting Items: Machinegun, Kill Healthenizer
Floor Start: Uptown (5-1)

Managed this quite easily with the zombie. Every person you kill becomes another zombie that will raise your electability for that floor. Usually just killing a few people will set off a chain reaction converting nearly the whole level. I was achieving very high electability for some floors with very little effort on my part.

The only hurdle to the run is being able to talk to the clerk in the mayoral village to set up the vote. You need to remove the "fair game" trait which makes most NPCs hostile to you. You also need to be able to communicate, either by removing the "vocally challenged" trait or by finding a translator which can be a quest reward or found in a crate. This costs $1500 + $600 which sounds high but you will find that you will be swimming in money due to the amount of deaths that occur per level.

I would suggest you leave your zombie followers the level before the mayoral village (floor 5-3) as they are liable to cause trouble.

make sure to have the no guns modifier for an even easier time.

Mafe72 guide is good and has some good pointers here is how I did this achievement.

Tank like
Trust funder
Wall walloper *
Walls worst nightmare

I have marked with ( *) these are your main go to traits some you may need to unlock via chicken nuggets

On mission 1-1 go forward and you will have a objective take him out and grab his knife then move to the left and you will see a house with two guards. Knock on the door and kill him.
The second guard will rush you open the safe and grab the sledgehammer you will be using this for the rest of the game.

Character I chose was the bartender for his charismatic trait seeing how you start off with everyone liking you so just do quests, save gorilla's to get the electability up as long as you are on +1 for floor it will deduct that from city which is overall electability.

Some levels you may not need to do extra quests or rescues so just concentrate on the main objectives.

On mission 2-2 (industrial) l think you will have a objective in the middle of the map you won't be able to pass the fire on the conveyor belt look underneath you there will be another building with a hacker recruit him and get them to hack the console and deactivate security which will stop the fire on the conveyor belt before you back out of the hacking menu release gas this will poison the guards.

Other tips try and grab a antidote and invincibility syringe which can be found on drug dealers.
What you want to do is use the clone machine and clone both items until you have three of each.

Learn the map it can be frustrating at first but you will get it done eventually I hope this helps you guys out.
