I liked it, but MASSIVE plot hole

In the beginning when the sheriff gives Vaughn a ride home, he hands him a flyer and says, "Election is this month, I'm your man". Well, wouldn't you know within that month Vaughn managed to be severely beaten, left for dead, with his chest and torso carved up. Yet he managed to get back to his feet (we dont know how long it took). He then later visits the Sheriff to press charges, the Sheriff says, "this wouldnt be about that incident at the casino a while back would it?"...a while back implying alot of time has passed. Well, on top of that statement, you have all the other events of the movie take place, Vaughn ends up going to a trial eventually for his crime, then before you know it he becomes the new sheriff of the town.

Soo, we're to believe ALL these events transpired within a month time frame in time for Vaughn to win the election?

Poor writing job, all the Sheriff had to say in the beginning was, "Election's coming up in a few months", or "later this year", and they would've easily eliminated that issue. Sounds like a script that was thrown together by a 12-yr old.
