My Fickle Fellow Citizens

I'm reading through the news, and I come across this: Bush Approval Rating Falls To 36%.

I've resigned myself to the fact that 52% of my fellow Americans decided that Bush was the best man to lead our nation for the next 4 years. But it kills me that now 15% of his supporters have changed their mind about him over the last year. It's insane - with the exception of Hurricane Katrina (which one can only vaguely blame Bush for, in a sort of "the buck stops at the President" fashion), things have pretty much been going according to plan. Even the most avid Bush supporter couldn't have expected our current situation to be any different - anyone with half a brain in their head knew that a year after the election the economy would still be sputtering (thanks to $3/gallon gas), people would still be dying in Iraq (we weren't going to pull out in 12 months no matter who won the election), the Republicans would still be pushing tax cuts for the rich and cuts in social services (duh), and Bush would try to fill the supreme court with judicial conservatives.

So I've gotta ask myself - why the hell did these people change their mind about Bush? What were they expecting? Were they not fucking paying attention during his first term? As I said, I could accept the fact that a majority of the voters supported Bush - I thought they were misguided, but OK, they have a different set of values than I do. But when a significant portion of them change their mind 12 months later, I have to figure that they don't actually have any values, and are just a bunch of gibbering idiots who don't put any more thought into their vote than "I'm gonna vote for the guy with the folksy twang in his voice".
