I can't speak for other states, but I am guessing that about 25 to 30% of those attending our Tea Parties here were registered Repubicans. There will probably be a lot more by November though if Democrats continue to try to squelch the Tea Party movement with schoolyard taunts and juvenile insults. But hey, whatever floats your boat.
The numbers disagree with you greatly.
They do? Please post the numbers reflecting party affiliation at our local Tea Parties. I was unaware that any such numbers existed, but then you are no doubt in a much better position to know about stuff like that than I am. After all, I was only there.
