May 18, 2010 -- Voters will take to the polls today for what's being called a "Mini-Super Tuesday" with an anti-incumbent twist.
Primaries are being held in Pennsylvania, Arkansas, and Kentucky, and there's a good chance that some veteran Senate Democrats, who are backed by the Obama administration, could be knocked out of office.
Sen. Arlen Specter, D-Pa., is in a tight race against Rep. Joe Sestak, D-Pa.,, whose netroots-backed campaign has seized on anti-Washington frustration.
In Arkansas, moderate Democratic Sen. Blanche Lincoln has support from the party establishment and the administration, but that hasn't been enough to hold back Lt. Gov. Bill Halter from surging in the opinion polls with the support of unions and liberal activists.
And the anti-DC fever isn't limited to the Democratic party. In a Senate primary in Kentucky, Tea Party-backed Rand Paul is poised to defeat Trey Grayson, who was hand-picked by Senate Minority Leader Mitch McConnell, R-Ky.
It could be the most important day of voting until the midterm elections in November and a bellwether as to how that election may go.
Our question to you today: Do you think it's time for a fresh set of faces in Congress?
