3. Todd Akin
There are a number of dodgy and stodgy politicians on this list, but Todd Akin is the worst of them all. In an August 19 television interview, when asked whether female rape victims who became pregnant should have the option of abortion, the Congressman responded that rape rarely leads to pregnancy and also implied that sometimes rape is all right ("If it's a legitimate rape, the female body has ways of shutting that down."). Excellent scientific assessment, Dr. Akin.
Worst of all, despite the public outcry, ridicule, and calls for him to drop out of his senate race, he merely said he'd misspoken and kept on campaigning like he hadn't just demeaned half of the population. Thankfully he caught a legitimate L in the election and had no way of shutting that down.
