Yesterday's primary races didn't bode well for the Washington establishment.
Right here in Pennsylvania, veteran U.S. Senator Arlen Specter lost his first-ever Democratic primary to Democratic Congressman Joe Sestak, ending his nearly 30 years serving in the U.S. Senate.
Tea Party favorite Rand Paul defeated Kentucky Secretary of State Trey Grayson in Kentucky's Republican U.S. Senate primary.
Meanwhile, neither incumbent Senator Blanche Lincoln nor Lieutenant Governor Bill Halter managed to get a majority of votes in the Democratic Senate primary in Arkansas. That race will be decided in a runoff election on June 8th.
