NRSC Planning Robocalls Aimed at Begich

New robocalls from the National Republican Senatorial Committee label Democratic Sen. Mark Begich as someone "whose answer to every problem is tax increases."

Beginning Wednesday, the committee plans to call thousands of Alaska households seen as likely swing voters, asking them if they agree that Begich "isn't working for the middle class."

The committee has seen Alaska as critical to Republicans' efforts to regain control of the U.S. Senate next year.

Begich is in the midst of his first term. Republicans who have announced plans to seek his seat include Joe Miller and Lt. Gov. Mead Treadwell.

Alaska's primary isn't until next August.
