By what measure do you say that? There is no central national Tea Party (yet). An the weaker candidates may have been early to seek Tea Party endorsement but some of the stronger candidates have been more cautious to court them openly. The effect of the Tea Party movement (if you want to call it that) will decide this election and the future of the country. It is about Patriots stepping forward. And don't ever underestimate the old grey eagles.
The least experienced candidates are the Tea Party favorites. A congresswoman with nothing special about her record. A corporate franchise operator who couldn’t get a win in a GA primary. Ideology trumps everything else, it seems. Christine O’Donnell syndrome.
