The Tea Party has put the Republicans in their place. They keep them from compromising, from reaching out to moderates and from thinking for themselves.
Best thing to happen for the Dems since Richard Nixon
I'm having trouble determining where you are drawing this idea from that the tea party is hurting the Republican Party. Last I checked, the Republicans are winning, not by a little, but by a lot. This is what you call hurting the Republican Party? Are you suggesting that if the former GOP of Dubya, the Republicans who pissed off the American people and lost control of Congress, was still today's GOP they'd be as successful in the upcoming elections as they are currently looking to be?
Your logic makes absolutely no sense. You're simply projecting your own feelings. You don't like what the tea party stands for and you fear their success so you are making claims that it's going to hurt the GOP because it makes you feel better to say that. There is no such evidence whatsoever to support your claim. I've never seen the Republican Party this energized since 94. If that's the result of them being "hurt" by the tea party then I'm sure their response will be "Thank you sir, may I have another!"
