In a new poll, Donald Trump holds an 11-point lead over Hillary Clinton in Indiana, where former Democratic Sen. Evan Bayh is up 7 percent over Republican Rep. Todd Young in the race for an open Senate seat.

According to the Monmouth University Poll released Wednesday, another 10 percent of likely Indiana voters say they support Libertarian nominee Gary Johnson.

Trump's popularity with 47 percent of respondents is likely bolstered by the presence of Indiana Gov. Mike Pence on the Republican ticket. Pence enjoys a 54 percent approval rating in his home state, the poll found.

But enough likely voters may be planning to split their ballots in November to deny Young the Senate seat presently held by a retiring Republican, Sen. Dan Coats. Bayh led Young 48 to 41 points despite his late entrance into the race.

The battle to replace Pence as governor of Indiana was a virtual tie between Lt. Gov. Eric Holcomb at 42 percent and John Gregg, former legislator, at 41 percent.

The Monmouth poll was conducted between Aug. 13 and 16 with 403 likely Indiana voters, producing a margin of error of 4.9 percent.
