I've often wondered this. I get that Tea party republicanss are more extreme, but fundamentally, what are the differences? Do they disagree on gay marriage, health care reform, taxes, government spending, gun laws, abortion? From what i can tell, the only difference seems to be that the Tea Party is more vocal on their beliefs, whereas regular republicans don't really seem to announce they're less popular views.
Like Chris Christie, for instance. He's supposedly a very moderate republican. How does he differ on the issues from the Tea Party?
