Montana Democrat Jon Tester voted against the DREAM Act last Saturday. While he was not alone, he did manage to upset one person who actually mattered a lot to Tester's being elected - Markos Moulitsas at the Daily Kos, one of the web's most popular blogs. Moulitsas is extremely influential with young liberals and he was able to raise a significant amount of dollars for the Tester campaign in 2006. Perhaps Tester thought there would be no consequences to voting no on DREAM, but Kos is furious and I wouldn't be surprised if he uses the site to promote a primary opponent for Tester.
