So who wants to join Rand Paul's "tea-party" caucus?
"I don't know about that," Sen. Bob Corker (R-Tenn.) replied with a nervous laugh. "I'm not sure I should be participating in this story."
Republican lawmakers see plenty of good in the tea party, but they also see reasons to worry. The movement, which has ignited passion among conservative voters and pushed big government to the forefront of the 2010 election debate, has also stirred quite a bit of controversy. Voters who don't want to privatize Social Security or withdraw from the United Nations could begin to see the tea party and the Republican Party as one and the same.
