It’s the end of an era. Michele Bachmann announced early Wednesday morning in a YouTube video on her campaign Web site (taking a cue from Anthony Weiner?) that she would not be running for reelection to the House of Representatives in 2014. Bachmann insisted her decision had nothing to do with the “recent inquiries into the activities of my presidential campaign,” but she did not address the recent congressional ethics investigation. She also said her decision “was not influenced by any concerns about being reelected,” despite her narrowest victory yet in 2012 against Democrat Jim Graves, who has already announced he is running in 2014. Never one to let her opposition to Obamacare go unmentioned, Bachmann said she will spend her last 18 months in Congress opposing the health-care law.
