One blogger says yes:
The tea party movement is dead. The one I was familiar with anyway. Judson Phillips held it down and Sarah Palin drove a stake right through its heart live last night on C-Span in front of an unsuspecting audience.
Sarah Palin didn’t give a tea party speech last night. She gave a partisan Republican address. It was a purely political speech designed to position her for a presidential run in 2012 or 2016. Period. She wasn’t there to celebrate the organic nature of a movement she had nothing to do with creating. She was there to co-opt the name and claim the brand as hers. And she did.
The movement, that came to be officially recognized almost a year ago but whose roots go back further than that, has been snuffed out and replaced in the public mind. The movement that began as a people’s movement of angry independent, libertarians and conservatives will now be thought as the movement of people like Palin, Dick Armey, Judson Phillips, Mark Skoda, etc. Essentially, a wholly owned subsidiary of the “Official Conservative Movement” and the Republican Party.
Strong words, but this much is sure — if Sarah Palin is the face of the Tea Party, then there is no room in it for libertarians.
