(CNN) - A new survey indicates that Sen. Jon Tester of Montana has his work cut out for him as he fights for re-election.
According to a Mason-Dixon poll conducted for five Montana newspapers, Rep. Denny Rehberg, the Republican challenger, has a 48%-45% edge over the first-term Democratic senator. Rehberg's three-point margin is within the poll's sampling error.

Six percent of likely voters say they're undecided, with one percent backing Libertarian candidate Dan Cox.
The poll indicates that Rehberg holds a nine-point 47%-38% advantage among self-identified independent voters. And the survey suggests a gender gap, with Rehberg leading by 14-points among men and Tester ahead by 13-points among women.
Tester narrowly beat incumbent GOP Sen. Conrad Burns by less than 4,000 votes in the 2006 election.
The Mason-Dixon poll was conducted Sept. 17-19, with 625 likely voters questioned by telephone. The survey's sampling error is plus or minus four percentage points.

Just why is Karl Rove spending millions in Montana to remove Sen. Tester? Montana is being flooded with outside monet from God knows where. I suspect China.
hopefully the northwest will wake up and see that repos are not the answer. For to long they have dominated the west and brought no advantages to the people only their own pocketbooks. Forward 2012
If I had this creep looking down his nose at me, I'd more than likely do one of two things. One would be laugh, the next would be spit.
Definitely time to dump the Democrat and get the seat back in the Republican column. It's the only way to get rid of Harry Reid and the Do-Nothing Democrat Senate he runs to cover for Obama's failures.
Thats to bad , Sen. Jon Tester is an honest guy.
If he voted for Obamacare, then show him the door Montana!! It is the ONLY way to get rid of Obamacare.
Tester is probably one of the best, most honest members of the US Senate.
It would be a shame if Montanans let the politics of the Tea Party get in the way of common sense. If our country is ever going to get beyond partisan gridlock in Washington, states like Montana need to elect people like this.
