In politics, we like to think voters pay attention to issues and remember what candidates are the screw-ups, the cheats, the nutjobs and the heroes. (I had to put that last because there aren't very many of them) What we tend to forget is that the voters don't care and don't pay attention. If I ran ads every day telling you Rick Perry raised your taxes, you would eventually believe me and not vote for him. Don't believe me? Here's a prime example of an average Texas voter's logic: "I really don't care which party they're with," she said while whisking through a convenience store on a recent afternoon. "If they'll just vote to lower taxes and for nothing else, really, I'll vote for 'em." [source]
