I require proof that there is a statistically significant difference in the voting patterns between so-called "Tea Party" Republican Congressmen and non-Tea Party Republican Congressmen.
I'm curious too. The only difference I see is that some of the Tea Party members are more social conservative.
I don't know where you're getting your information from. But the main platform of the Tea Party emphasizes cutting spending and lowering taxes, the 'social conservative' aspect is downplayed. In fact the Tea Party evicted for making anti-gay comments if I recall right.
