Republican senators are "united" around the party's slate of candidates, Sen. Jim DeMint (R-S.C.) asserted Tuesday.

DeMint, the supporter of several successful conservative candidates in hotly-contested GOP primaries, said he'd met with National Republican Senatorial Committee (NRSC) Chairman John Cornyn (Texas) about rallying around GOP nominees.

"I just met with John Cornyn, who is the chairman of our Senate committee that supports candidates," DeMint said on Fox News. "I support all of our Republican candidates, and so does John Cornyn and Mitch McConnell. Our party is united around our slate of candidates, and we've got the energy of the grassroots movement out across the country right now."

Much has been made of DeMint's support of insurgent candidates through his Senate Conservative Fund, many of whom managed to beat NRSC-recruited candidates.

In the wake of Christine O'Donnell's win two weeks ago in Delaware, reports swirled about whether DeMint would use his newfound clout to make a presidential bid, or challenge members of the Senate Republican leadership. DeMint's said he plans neither.

Rather, DeMint claimed, the conservative primary challenges show that the GOP is really a "big tent" party.

"What this is showing is that the people who really want a big tent Republican Party are conservatives. When the moderates can't win, they change parties. And I don't think the people of Alaska or Pennsylvania or Florida appreciate that," he said, alluding to the decisions by Sen. Lisa Murkowsi, Sen. Arlen Specter, and Gov. Charlie Crist, respectively, to leave the GOP after losing or trailing badly in primary races.
