Brief summary: Ned Lamont and Joe Lieberman are involved in a primary election today for Lieberman's senate seat in Connecticut. Lieberman is for the war in Iraq. Lamont is against it. The smart people of Connecticut will throw Lieberman out of office for supporting the war and elect Lamont.
This scares the heck out of the Republicans because some believe that a Lamont win will signal that many other pro-war incumbents will be thrown out of office in the mid-term elections this fall.
Today Fox News threw up this graphic. (Click to enlarge.). Not very fair. Not very balanced.
