Republican candidate Richard Mourdock (left) and Democrat candidate Joe Donnelly.

(Indianapolis, Ind.) – Two new polls indicate that it could be a very tight race for Indiana’s U.S. Senate seat.

Republican Richard Mourdock – who ousted longtime incumbent Senator Richard Lugar in the May primary - and Democrat Joe Donnelly face off on the November ballot.

A poll by the left-leaning Majority PAC and Center Forward shows Donnelly with a two point lead over Mourdock, 45-43 percent. Twelve percent of 601 likely voters polled were undecided. The poll had a margin of error of +/- 4 percentage points.

However, a poll by the right-leaning Indiana Chamber of Commerce gave Mourdock a 41 to 39 percent lead with 17 percent undecided. It questioned 600 likely voters and had the same +/- 4 percent margin of error.

Political experts believe the undecided voters, most of which identified themselves as Republicans, could tip the election in Mourdock’s favor.

The Chamber of Commerce poll also showed Indiana U.S. Congressman Mike Pence has a significant lead over Democrat John Gregg in the race for the Governor’s office. Pence leads 50 to 32 percent.
