DAVID GREENE, HOST:
In Kentucky yesterday, there was another sign of Tea Party clout. Mitch McConnell - minority leader in the U.S. Senate, and Kentucky's most powerful politician - turned up at his first-ever Tea Party rally. [POST-BROADCAST CORRECTION: This was not McConnell's first Tea Party rally. He participated in a Tea Party event in 2010.] This year, Tea Party candidates have scored upsets in Republican primaries in Missouri, Texas and Indiana. That's where longtime Senator Richard Lugar lost.
