Franken to run for Senate

It's official - Comedian and left-leaning Commentator Al Franken said today he will run for U.S. Senate in 2008, confirming his long-suspected plans to seek the Democratic nomination to challenge Republican Sen. Norm Coleman.

Franken's announcement came on the final day of his radio show on Air America. Franken took his career in a political direction when he wrote "Rush Limbaugh Is A Big Fat Idiot and Other Observations."
