I don't think the Tea Party is open to Jewish people. Too many in that organization believe we are the source of their agony, be it the age old "Zionist Conspiracy," "Foreign Banksters," or "Dual Nationals," it all equates to distrust of Jews.
Go to Alex Jones' conspiracy site, read the comments under any news story, see what so many in the Tea Party really say under the anonymity of the internet, and then tell me I'm wrong.
