Sen. Jim DeMint (R-S.C.) is endorsing a lot of Senate candidates running against the GOP establishment. But that won't be the case if Dino Rossi runs in Washington state.

DeMint told the Ballot Box that, if the former gubernatorial candidate gets in the race, Rossi can expect his support - and that of his Senate Conservatives Fund.

"Rossi certainly would be a great candidate," DeMint said. "I’m almost certain he would have our full support if he jumped in."

DeMint this week endorsed state Sen. Marlin Stutzman in Indiana and last week backed Weld County District Attorney Ken Buck in Colorado. Both are running underdog campaigns against party establishment favorites.
