After suggesting that Barack Obama had anti-American views in an exchange three weeks ago with MSNBC host Chris Matthews, Rep. Michele Bachmann (R-Minn.) told Politico Thursday that she was “extremely grateful that we have an African-American who has won this year.” She called his victory “a tremendous signal we sent.” “People knew that I am a serious member of Congress, that I take issues seriously, and that I worked extremely hard. ... They know I’m not a nuanced politician that waffles and changes my mind with whatever is popular at the moment.”
