Poll give Rehberg slight lead

HELENA (AP) — A new poll shows Montana's U.S. Senate candidates continuing to run in a tight contest.

A Lee Newspapers of Montana poll found Republican Denny Rehberg, a six-term member of the House, supported by 49 percent of respondents. Incumbent Democrat Jon Tester had 45 percent. Libertarian Dan Cox had 1 percent and 5 percent said they're undecided.

Mason-Dixon Polling and Research Inc. of Washington, D.C., polled 625 registered voters on both cellular and land-line phones from Monday through Wednesday. The poll's margin of error is plus or minus 4 percentage points.

The race could help decide control of the Senate, where Democrats hold a bare majority of 51 seats.
