Control of the U.S. Senate is up for grabs in this year's mid-term general election and insiders say it could come down to races in as few as seven states. Senate races in four more states, including Oregon, also could play a role.
The political wildcard in the election deck is what happens in Republican primaries, including in Kentucky where Senate Minority Leader Mitch McConnell is facing a Tea Party challenger. In 2012, GOP voters nominated very conservative and controversial candidates that cost them victory in November in at least two states.
Oregon Democratic Senator Jeff Merkley won't have a walk-over in his first re-election bid, as credible Republicans, including Rep. Jason Conger of Bend, have jumped into the race. Expect some big money to come to Oregon to bludgeon Merkley. If that works or Merkley slips, Oregon could wind up on the short map of key races to decide control of the Senate.
For now, Washington Post political analysts point to Alaska, Arkansas, Louisiana and North Carolina as the battlegrounds to watch with Democratic incumbents trying to stave off GOP challengers. Republicans are given the edge to win seats in Montana, South Dakota and West Virginia, where Democratic incumbents are retiring or, in the case of Montana Senator Max Baucus, heading off to the China as the new U.S. ambassador.
