The way I see it, the pols get married in part because they know that dumbasses get married. Dumbasses like it when people act like them. Sort of the "have a drink with him" type of mentality. And a dumbass's vote is worth just as much as anyone else's vote. Dumbasses also tend to think that marriage = good (sometimes even if they are not married, but think it's a good idea). And since smart folks realize that "married" does not equal "good leader," they figure they can catch more fish by being married.
