Rep. Michele Bachmann is the leader of the Tea Party Caucus. She thinks that climate change is voodoo nonsense, hokum, AND a hoax. She said in 2008 that she was "very concerned that he [Obama] may have anti-American views." She wants to "wean everybody off" Social Security and Medicare. She has said terrible things in reference to homosexuality and same-sex marriage. But my main issue with her is that she's clearly just not that bright.
She apparently thinks HPV vaccines cause mental retardation, on the basis of one anectdotal report from the campaign trail. That she could be so easily convinced shows her lack of scientific insight and knowledge. That she would pass along the claim in a national interview shows her lack of political instincts. This episode, along with a long history of misstatements and/or fabrications, as well as having never in her 4+ years in Congress written a single bill that has become law, shows that she just doesn't have the intelligence or ability to be President.
But there is a path for her to win her party's nomination, which in this economic and political environment, gives her a path to the White House. Her campaign was doing very well, including a win in the Iowa Straw Poll, until Gov. Rick Perry entered the race. He has taken over much of her support as the Tea Party "anti-Romney". It is unlikely that Bachmann will win the nomination unless Perry is knocked out of the race.
Bachmann seems to recognize this, given the vigor with which she attacked him at the last debate. Her attacks regarding Perry's decision to mandate the HPV vaccine in Texas, along with pointing out possible corruption on Perry's part (more on that in my post about him) have managed to hurt Perry somewhat, particularly in the head-to-head with Obama.
Hopefully, even if Bachmann were nominated, the months of scrutiny of her record and her abilities would prevent her from being elected. But one can never be too sure.
