Politicians like Steve Daines, Mike Rounds and Shelley Moore Capito aren't household names to most Republicans. But they could be the keys to the GOP reclaiming the Senate in 2014.
The party needs to gain six seats to claim control of the chamber. Daines, Rounds and Moore Capito are the likely Republican candidates in Montana, South Dakota and West Virginia, respectively, where retiring incumbent Democrats have created openings for the GOP.

Michigan and Iowa will also see incumbent Democrats retiring next year. Sens. Mark Begich of Alaska, Kay Hagan of North Carolina, Mark Pryor of Arkansas and Mary Landrieu of Louisiana are all running for re-election but are expected to face challenges. In all, nine Dem-held seats are seen as potentially vulnerable next year.
On the other side of the aisle, Sen. Mitch McConnell, R-Ky., will face a tough re-election fight against Democrat Alison Lundergan Grimes.
Additionally, the retirement of Sen. Saxby Chambliss, R-Ga., creates an opening that Democrat Michelle Nunn hopes to exploit.
