The Tea Party is the new Bush. The Democrats demonized Bush to win in 06 and 08. They are trying to do the same thing to the Tea Party.
It won't work. The Tea Party consists of millions of American taxpayers - the ones who actually pay for everything. They're the wrong people to be attacking right now.
Bush was a single person. The left was able to isolate the target. They can't do that with the millions who hold the purse strings. It's like the old saying goes - "Never bite the hand that feeds you."
No spending or tax revenue by the Tea Party or it's supporters - no money in Washington for the democrats to buy votes with.
