Limbaugh: Obama will 'lose big'

Talk show host Rush Limbaugh, who for weeks has promoted Hillary Clinton to keep the Democratic race going, changed course today and pushed Barack Obama.

Obama would be the weakest nominee, declared Limbaugh, who told listeners that Obama "has shown he cannot get the votes Democrats need to win -- blue-collar, working class people. He can get effete snobs, he can get wealthy academics, he can get the young, and he can get the black vote, but Democrats do not win with that."

"He will lose big," Limbaugh predicted.

Clinton, in more palatable language to Democrats, basically makes the same argument to say she would be the stronger nominee in November.

Limbaugh -- who credits his "Operation Chaos" for Republicans crossing over in open primaries such as the one in Indiana on Tuesday to support Clinton -- "released" Democratic superdelegates to "get in the tank" for Obama, but also urged Clinton to stay in the race.

"You've come too far to quit," he said.
