Democrats Keep Senate: Warren, McCaskill Win

Democrats had a banner night in the Senate, starting with Elizabeth Warren knocking off GOP incumbent Scott Brown in Massachusetts. Meanwhile, Tim Kaine beat George Allen in Virginia, and Chris Murphy did the same to Linda McMahon for Connecticut's open seat—despite her huge personal influx of cash. It gets worse for the GOP: Republicans Richard Mourdock and Todd Akin each lost, making it certain that Democrats will retain control of the Senate, reports AP. Their cushion stood at 53-47 heading into the night.

• Indiana: Democrat Joe Donnelly beat incumbent Mourdock, who ran into hot water over abortion comments.
• Missouri: Incumbent Claire McCaskill beat Todd Akin, who seemed on track for a win until his "legitimate rape" controversy.
• Ohio: Democratic incumbent Sherrod Brown fended off Republican Josh Mandel.
• Maine: Independent Angus King won as expected. The former governor still won't say with whom he'll caucus, but it's expected to be Democrats.
• Pennsylvania: Democrat Bob Casey defeated businessman Tom Smith.
• Texas: Tea Party favorite Ted Cruz won the race for outgoing Republican Kay Bailey Hutchison's seat, reports the Houston Chronicle. The victory will make him the third Hispanic member of the Senate.
• Wisconsin: Democrat Tammy Baldwin defeated former Gov. Tommy Thompson, which will make her the first openly gay senator.
