True, he was elected and re-elected by a small turn-out. But that apples to all politicians. It cannot just be a critique of Prozanski. 
As far the majority that are ignored, it is the low-income and youth that tend to vote less. If they don't vote, their voice won't rise above those who do. 
As far as your other dislikes (like "sweaty and sagging" people), they have no relation (that I can see) to the fact that Prozanski gets re-elected in this democratic system. 
But Eugene does not seem a good place for you. Can you name a town you like better?
