Tonight, Republican U.S. Senate candidates Todd Rokita, Luke Messer and Mike Braun will participate in one final debate before the May 8 primary.
The debate, which is sponsored by the nonpartisan Indiana Debate Commission, begins at 7 p.m. and will be broadcast across the state.
The candidates have gone toe-to-toe in previous debates, each trying to gain some traction in a bruising primary that has seen its fair share of controversy.
An early-April poll by Gravis Marketing found Braun leading the two U.S Representatives with 26 percent of the vote, Rokita and Messer well behind at 16 and 13 percent, and nearly half (46 percent) of the 411 likely voters polled saying they were uncertain who they would vote for.
The winner of the heated primary will face Joe Donnelly, the Democratic incumbent who has no primary challenge.
