This may have been mentioned in another thread, but in case you haven't seen it:

In short, according to the Dartmouth study, the Republican Party either (a) loves deficits or (b) is living in fantasy land...
Personally, I think it's a mix of the two. I think the saner Republicans actually don't care about the deficit. And most of the base, the Fox News crowd if you will, are deluded souls hanging on for dear life to the myths of Reaganomics.
I've always been registered third-party, but I never thought I'd actually be totally opposed to the Republican Party. However, somehow they've become completely disconnected from reality, and that's a sure deal-breaker.
