WASHINGTON — A Democratic push to boost the federal minimum wage to $10.10 an hour is a long shot in Congress this election year, even after President Obama made the increase a centerpiece his State of the Union address.

There is little suspense over the outcome. Few expect Democrats to muster the 60 votes needed in a showdown Senate roll call that Majority Leader Harry Reid, D-Nev., wants on the minimum wage by early March. Even if they do, the Republican-run House rejected a similar plan last year and seems unlikely to revisit the issue soon.
