SENATE RACE – Tester Confident of Voting Record

Sen. Jon Tester says he is confident his record will stand in his re-election challenge from Republican Rep. Denny Rehberg.

Tester formally filed with state officials Tuesday to appear on the ballot. The Democrat who came from behind to topple former Sen. Conrad Burns in 2006 is seeking a second term.

The race between Tester and Rehberg is already a multimillion-dollar slugfest expected to only receive more attention as November draws near.

Tester is being attacked as an ally of President Barack Obama. Tester says he does not regret votes in favor of health care reform because he argues it will help fix a broken system.

Tester counters that he thinks Rehberg has been guilty of "irresponsible decisions" while serving in Congress for more than a decade.
