So much for talk of conservative radio-host Rush Limbaugh's hosting a Republican presidential debate.

Limbaugh said today there's "no question" that a Limbaugh-moderated debate would get high ratings, but his star power would overshadow the event.

"I don't see how I can, I'm too famous," Limbaugh, 62, said on his show today.

The comments come after Republican National Committee Chairman Reince Priebus suggested that instead of having "mainstream media" networks moderate party debates, Limbaugh and other conservative radio pundits could.

Asked by Fox News Channel-host Andrea Tantaros earlier this month about the possibility of a debate hosted by Fox News' Sean Hannity and conservative radio-host Mark Levin, Priebus threw his support behind the idea.

"I actually think that's a very good idea," Priebus agreed. "I mean, there's a lot of good people out there that can actually understand the base of the Republican Party, the primary voters."

Priebus has threatened NBC and CNN with pulling out of Republican debates if both channels go forward with plans to air a miniseries and movie about former Secretary of State Hillary Clinton, a presumptive 2016 candidate, before the election.
