What she won: Current Missouri senator Claire McCaskill kept her seat by defeating her Republican challenger Todd Akin.
Why it's important: Yep, she beat that Todd Akin . . . you know, the one who said victims of "legitimate rape" can't get pregnant. At the time, Claire had responded to the comments by saying, "I have a hard time imagining a woman uttering the phrase 'legitimate rape.' It is not something that would ever come out of a woman's mouth, because it is something every woman is fearful of. I think every woman knows someone who has had to deal with sexual assault."
