Bush was a RINO, and he revealed himself almost from day one of his administration. It's unfortunate, actually. I sometimes wonder if it would not have been better to endure Al Gore during that time period. Under a Gore administration, it's unlikely he'd have taken the steps necessary to get us out of the Clinton recession, and this mess we're in now would have started a lot sooner, what with the "Housing Crisis." The causes of it, I think, might have come to the fore far sooner.
But, a little pain is better than long term decline, IMHO. McCain would have been a disaster regardless. I truly think the man has something wrong in his head. I heard an interview done by Michael Reagan during the 2000 primary campaign, and the man came out as a complete conspiracy theorizing kook. Not sure if that interview is online or not, but it was truly fascinating to listen to. I was actually surprised the Obama camp didn't dig it up during the presidential campaign. Had it been played for a national audience, Obama might have won by a landslide.
