WESTVILLE, Ind. (AP/NETWORK INDIANA): Indiana’s three U.S. Senate candidates will face off in the first debate of the general election campaign.

Incumbent democratic Sen. Joe Donnelly, Republican former state Rep. Mike Braun and Libertarian Lucy Brenton will take the stage Monday night at 7 p.m. at the Purdue University Northwest campus.

“When you talk about these national issues, trade, you talk about tariffs, steel, aluminum, soybeans, you talk about the ag sector, all of these things have a real impact in Indiana,” said Gerry Dick, with Inside Indiana Business, looking ahead to the debate.

The race is expected to be one of the most closely watched in the U.S. and could determine which party controls the Senate next year.

Most of the questions that the candidates will answer have been pre-selected by the Indiana Debate Commission and were submitted through their website.

Braun and Donnelly are neck-and-neck in recent public opinion polls.
