"This is a symbol that the tea party movement and the broader limited-government agenda is huge."

"It's the center of American politics. It's everything that we've been saying it is. It's not just a protest movement; it's a political force."

The shocking defeat of a long-term senator — Sen. Robert F. Bennett — for the Republican Party nomination in Utah.

The response from Timothy M. Kaine, chairman of the Democratic National Committee:

"That the Tea Party would consider Bob Bennett -- one of the most conservative members of the U.S. Senate -- too liberal just goes to show how extreme the Tea Party is. This is just the latest battle in the corrosive Republican intra-party civil war . . . If there was any question before, there should now be no doubt that the Republican leadership has handed the reins to the Tea Party."

He sounds upset.
