INDIANAPOLIS -- A little-known Republican challenging Sen. Evan Bayh is fueling controversy with some comments made before a guns rights group.

Political newcomer Richard Behney told a meeting of a Second Amendment Patriot group in Evansville that it's essential to vote in new faces this November.

"I've got news for Barack Hussein Obama and, in my case, Evan Bayh. In 2010, we ain't calling you out, we're throwing you out," he said in a speech later posted on YouTube. "Because, if we don't see new faces, I'm cleaning my guns and getting ready for the big show, and I'm serious about that."

Behney told 6News' Norman Cox that he wasn't threatening anyone, but simply expressing the fear and concern he's heard from thousands of Hoosiers.

He said he believes that if unresponsive politicians continue with out-of-control spending, the United States will wind up like Haiti, with a collapsed economy and broken down society, forcing Americans to arm themselves to defend their homes.

"If we continue down this road in the years to come, we could find ourselves in the same position, and in a position where we literally would find ourselves defending our families," Behney said.

Behney, who is best known as the owner of the Atta-Boy plumbing firm, said his disgust with excessive government spending led him into the Tea Party movement, and now into the Senate race.

Three other Republicans -- former U.S. Rep. John Hostettler, State Sen. Marlin Stutzman and Richmond financial adviser Don Bates, Jr. -- are also competing for the chance to challenge Bayh.

The primary will be held on May 4.
