On August 8, 2006, the incumbent Democratic Senator from Connecticut, Joe Lieberman, lost his primary race to challenger Ned Lamont by 52%-48%, and then ran as an Independent in the general election. A great deal of attention was focused on this race as an early barometer of both anti-incumbent and anti-war sentiment nationwide. Comparisons were made between Lieberman's troubles and Cantwell's re-election bid, citing Cantwell's vote in favor of the Iraq Resolution that led to the war, her refusal to say she regretted the vote, and her vote against a timetable for withdrawal.
