Currently, the GOP seems poised to pick up between one and three Senate seats, short of the four needed to win control of the chamber.
Republican hopes for taking the chamber suffered a hit after Rep. Todd Akin's (R-Mo.) comments in August, that the female body can prevent pregnancies in cases of "legitimate rape," created a political firestorm. Those comments helped his opponent, incumbent Sen. Claire McCaskill (D-Mo.), stay competitive in her bid for reelection.
Republicans appear likely to comfortably retain control of the House of Representatives.
