This article is a good start at documenting her history of batshitcrazy. There are so many quotes to choose from...
Your guide to the Minnesota firebrand's most outrageous, outlandish, and out-there remarks.http://motherjones.com/politics/2011/06/michele-bachmann-greatest-hits?page=1 2004: Songwriter Melissa Etheridge has breast cancer. That's bad news. But there's good news too, Bachmann tells the conservative education group EdWatch: maybe the cancer will give her time to reflect on her sinful lifestyle: "Unfortunately she is now suffering from breast cancer, so keep her in your prayers. This may be an opportunity for her now to be open to some spiritual things, now that she is suffering with that physical disease. She is a lesbian." In the same speech, she alleges that "almost all, if not all, individuals who have gone into the lifestyle have been abused at one time in their life, either by a male or by a female."
2008: Just two weeks before election day, Bachmann calls for an investigation into the anti-American ambitions of Barack Obama and congressional Democrats: "What I would say is that the news media should do a penetrating expose and take a look. I wish they would. I wish the American media would take a great look at the views of the people in Congress and find out if they are pro-America or anti-America."
2011: In an address to the group Iowans for Tax Relief, Bachmann praises the Founding Fathers for their commitment to…diversity: "It didn't matter the color of their skin, it didn't matter their language, it didn't matter their economic status, it didn't matter whether they descended from known royalty or whether they were of a higher class or a lower class, it made no difference. Once you got here
you were all the same. Isn't that remarkable?"
