Sen. Jim DeMint's (R-S.C.) Senate Conservatives Fund has raised more than $200,000 for Indiana Senate candidate Marlin Stutzman as the state senator looks to pull an upset of former Sen. Dan Coats (R-Ind.) in the GOP primary.

The haul equals the $200,000 that Coats loaned his campaign and should allow Stutzman to continue to build up his name ID in advance of Tuesday's vote. Stutzman has emerged over former Rep. John Hostettler (R-Ind.) as Coats's biggest obstacle to the GOP nomination.

The endorsement of DeMint has paid big financial dividens for Stutzman. Through April 14, Stutzman had raised just $260,000 and had just $45,000 on hand.

Before loaning his campaign $200,000 last week, Coats had raised $445,000, albeit in a shorter time period than Stutzman.

"This race is still wide open, and Marlin is gaining momentum with a clear conservative message," DeMint said. "The response from the grass roots in Indiana and across the nation has been remarkable. Marlin is raising money $25 at a time from thousands of people who want to send a new generation of conservative leaders to Washington."
