Town must work together to figure out who Lee Harvey Oswald and his mysterious accomplice are, and lynch them before they kill JFK. Each one could clear himself by giving a clue about the president if they dare. However beware, if those clues are too blatant Oswald can win.
If you're random lynched it is your own fault for being slow, usually the person that is lynched is the first person to be voted (granted that Maf doesn't vote Pres) - get faster.
Don't instantly follow bandwagons, keep occasionally switching votes around randomly as town and pretend you settled on a non-president role accidentall.
