With barely two weeks to go before Republican voters pick a Senate nominee, competitors rolled out endorsements Monday from prominent conservatives.

State Sen. Marlin Stutzman touted backing from David Keene, the chairman of the American Conservative Union, who said that “the problems we have today require a new generation of conservative Republican leadership.”

Former Sen. Dan Coats (R), whose campaign has been promoting his 90 percent lifetime score from the ACU, later Monday announced an endorsement from James Dobson, the founder of the Focus on the Family. Coats’ campaign said it would begin airing a radio ad featuring Dobson that will run statewide through the May 4 primary election.

The third major Republican candidate in the race is former Rep. John Hostettler, who last week won the endorsement of another big name in conservative politics, Rep. Ron Paul (R-Texas).

The likely Democratic nominee is Rep. Brad Ellsworth.
