"I now believe he would be the weakest of the Democrat nominees," Limbaugh, among the most powerful voices in conservative radio, said on his program. "I now urge the Democrat supereldegates to make your mind up and publicly go for Obama."
"Barack Obama has shown he cannot get the votes Democrats need to win – blue-collar, working class people," Limbaugh also said. "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."
For months, Limbaugh has urged his listeners in states with open primaries to cross party lines and support Clinton in an effort he has dubbed "Operation Chaos." The conservative talk show host has said the Republican Party will benefit from a protracted Democratic race that grows more bruising by the week.
