Senate Democrats are hoping they can keep their majority in the upper chamber, but for a handful of the 23 seats at stake for the Democrats, maintaining the majority means more than riding President Obama's coattails, if indeed he has any. Instead, at the state level, where Obama is unpopular, some candidates will claim independence, reports National Journal's Dan Friedman. Here's a look at those senators:
Sen. Sherrod Brown, D-Ohio.

Sen. Bob Casey, D-Pa.
Political Hurdle: Like Brown, Casey comes from a state where the trade agreements the president worked on with Congress are unpopular. Casey touts his support for get-tough legislation on currency manipulation.(AP Photo/Alex Brandon)
Sen. Joe Manchin, D-W.Va.
Political Hurdle: Keeping as far away from Obama as possible. Manchin came to the Senate 15 months ago and aims at avoiding association with the president. "That's not my style," he said when asked if the president ever called him.(AP Photo/Jacquelyn Martin)
Sen. Claire McCaskill, D-Mo.
Political Hurdle: Contrasting her views with Obama's where appropriate. "There are places I agree with the president. There are places I disagree with the president," she said.(AP Photo/Manuel Balce Ceneta)
Sen. Bill Nelson D-Fla.

Sen. Debbie Stabenow, D-Mich.

Sen. Jon Tester, D-Mont.
Political Hurdle: Senate Democratic leadership and the administration favor the Dream Act, unpopular with conservatives in states like Montana. Some Democratic strategists worry that the act might inspire conservative opponents more than Democratic supporters.(Liz Lynch)
