What killed me about Bush is the absolutely shameless, Orwellian levels of propaganda and willful blind spots surrounding him. For five years we heard seemingly nothing but praise and justification for this asshole, with the right-wing media working overtime to convince us how wonderful his administration was. To say nothing of the "if you question him, it's because you want the terrorists to win" mentality. Never mind the rest of the country, there were plenty of Republicans who knew this guy was a total dud, but the entered into one of the creepiest, Kool-aid sucking states of denial I've ever seen for the good of their party. These people would have insisted the sky was green if that was the Republican party line. And these were not stupid people, despite what you may want to believe. I spent a lot of time hanging out on conservative message boards during the Bush years to try and understand the mentality. While there were plenty of sub-humans, there were some that actually engaged me in debate, and it was obvious that they were smart people who were lying to themselves about Bush and the GOP. The simple fact is, the Republicans became politically mighty over the last couple of decades by moving in lockstep support of their candidates, and during the Bush years they tried to keep this going against every common-sense tendency in their bodies.
And they did, in fact, manage to get Bush over the finish line, but (to continue the analogy) at the cost of having the wheels fall off and the engine explode as soon as they'd done so. I swear you could feel the mass unpuckering of Republican sphincters in late 2006, after it stopped being necessary to pretend that Bush was awesome. At which point they tried to go into a combination ignore/repudiate mode ("Bush was never a real conservative", said the people who would have called you a traitor for not voting for him in 2004) but it just didn't work. People were tired of believing six impossible things before breakfast every day, they saw another four years of it coming up with Palin, and it was too much for them. The Tea Party was a good try (being the opposition always makes it easier to promote all the wonderful things you WOULD do but can't) but again, these guys succeeded too fast, got into Congress, and proved themselves to be an even bigger debacle, and all the wind went out of the movement. The cognitive dissonance has become too much for most people, especially now with Bin Laden dead, the economy improving, and not much to be immediately terrified about (just, y'know, the usual long-term things). The current GOP meltdown has been a LONG time coming, and it has its roots in the Bush era. As much as he fucked things up, I can't help thinking we're going to see the political pendulum swing back for a nice, long arc to the left, thanks mostly to what an obvious disaster he was.
