Election Day

 is a minor quest in Fallout 3.

Dave is running for President of The Republic of Dave once more and he needs your help. He asks you to talk to the other four adults of his land (Jessica, Shawna, Rosie, and Bob) to get them to vote. Once you have talked to them, go back to Dave and receive your reward.

There are a total of 5 votes, including Dave's. It is possible to persuade Rosie and Bob to run against Dave in the election. Doing so would net them each one vote (if they haven't voted yet). Under normal circumstances they would only receive one vote, presumably their own.

It is not yet known if anything other than convincing citizens to run would have any effect on the result, there may be an alternate way to complete the quest other than rigging the election.

Under normal circumstances, other candidates will not win. They would at most receive one vote (presumably from themselves). The only way to get Rosie or Bob to win is to steal the other ballots for Dave out of the box before he counts them all.

Rigging the Election
After you have told Dave all the votes are in, he will go to the ballot box. If you are quick enough open the ballot box right after Dave unlocks it, steal all the votes, but leave one vote for the candidate of your choosing. Dave will count the votes and declare whomever you left a vote for as the winner. If you speak to the victor he or she will give you the code to the safe. It contains a unique Rifle named Ol' Painless, which has a faster rate of fire and does more damage. The rifle can be repaired with regular hunting rifles.

Dave will get angry and say something about leaving then storm out of the Republic. If you catch Dave as he leaves the camp he will tell you that he is going to Old Olney to liberate it from the wasteland and create a new Republic. Due to the Deathclaw infestation in Old Olney, you can usually find Dave dead on the streets somewhere. You can opt to 'escort' (i.e., follow) him to Old Olney and kill any robots, bloat flies and Deathclaws you encounter. He will finally park himself in an alleyway and say something like "This is the New Republic of Dave. Go away." After being talked to three times, he will attack you.

Alternatively the player may decide to use this quest as a method to more sneakily complete the You Gotta Shoot 'Em in the Head quest and avoid the residents being turned hostile (assuming you don't have any interest in talking Dave into giving up his key). To use this method, make Dave lose the election and when he leaves follow him a short ways away from The Republic of Dave (so the residents don't witness the murder) you can then "shoot 'em in the head" without killing or being shot at by the Republic of Dave residents.

If you take Ol' Painless from the safe you will receive negative karma, even if you have the key. If you then speak to someone from the town, it is possible they will take Ol' Painless from you. If this occurs the only way to get it back is through more negative karma of either pickpocketing it or killing them and looting it.

Bugs
Several people report that this quest is easily broken. If you convince both Bob and Rosie to run for president and either: Remove all votes, leaving the ballot box empty OR Remove all Dave's votes, leaving one for Bob and one for Rosie Dave will state that Rosie won, storm off, and: Bob's conversation will contain only the "sorry you lost" dialogue option AND Rosie's conversation will contain only the "sorry you lost" dialogue option 
 * The voters don't vote after being told to do so, they just stand in front of the ballot box, doing nothing; a work around after reverting to a previous save, is to ensure you give a full minute in between telling each to vote. The bug is pathing conflicts with no specific NPC having path priority. This can also being avoided by telling them to vote one at a time, following one and waiting him to vote and go back to what he was doing before asking the next to vote.
 * The NPC Shawna can die from mysterious circumstances and her body is never found. Bob, Jessica, and Rosie tell you Shawna died but Dave seems to have no idea. If this happens, Shawna cannot be told to vote and the quest cannot be completed. Also it's possible that, after talking to Dave, there's no entry in your quest log, i.e. the quest is not properly triggered.
 * To fix the problem with the people standing in front of the ballot box, doing nothing: Open the console (~) click on the frozen person and type in "resurrect" press enter. They will respawn and vote. (This works well for many problems with frozen people in Fallout 3 as well as in Oblivion)
 * If Dave does not win the election, the victor would reward you with the code to the safe. Even so you will get karma penalty for taking items from the safe (including Ol' Painless). Items are considered stolen.
 * If you convince Bob and Rosie to run for president and rig it so that they tie, Dave stays as president. He should say "There was a tie. Under these unique circumstances, I'll have to remain the leader until we know the results for sure" which is one of the dialogs in the game files, but in-game he would often say either Bob or Rosie won, and not leave the republic.
 * If you open Dave's safe after getting his key, he will attack you. If you kill him and the other people who attack you in the room, then Bob becomes the new president.
 * When all the votes are cast (All electing for Dave) Dave will begin to read out the votes. When you steal from the ballot box whilst they are being read, removing all the votes, Dave will continue to say that another vote is for him. Then he will pause and ask if the box has been tampered with then go on to say that Rosie has won the election although there were no votes inside. After the speech about leaving Almighty Republic of Dave because of his loss, he will continue to stay in town like nothing has happened. Anything about the elections in the dialog will be removed.
 * On the PS3 Version (maybe other platforms as well) you might not get the quest activated, but the voting will go on. Dave says Rosie (might even happen with Bob) won, and says he will leave and see how the town will survive without him. But when talking to her she says she lost and there will always be another election. This might cause problems getting Dave's Key for his safe in which you can find the Unique Hunting Rifle Ol' Painless. The few things you can do when this happens is to load a savefile, pickpocket Dave, or kill him.
 * Bob and Shawna will sometimes die from Death Claw attacks; the others will remain safe because they stay in the house.
 * Under unknown circumstances, Dave will treat the filing cabinets to his right as the ballot box. This was encountered on the 360.
 * If both Bob and Rosie are running and you remove all but Bob's vote, Dave's conversation cuts off right before speaking the winner's name. He then leaves for Old Olney without throwing his tantrum.
