Rush Limbaugh has clearly fallen out of love with Rick Perry.

When the Texas governor was considered a presidential race, the renowned radio host delivered a 20-minute monologue extolling the Texas governor as the kind of anti-Washington conservative who could drive Democrats “nuts” and pierce President Barack Obama’s aura of re-election invincibility.

When Perry ran into some trouble in Republican debates, El Rushbo rushed to his defense.

No more.

After Perry described rival Mitt Romney’s work at Bain Capital as “vulture capitalism” (rather than venture capitalism), Limbaugh lashed out.

“That is indefensible!” he said on his EIB broadcast today. “It’s absurd…this is the language of leftists! This is the way Fidel Castro thinks, or says he thinks.”

As you probably know, Limbaugh is no fan of Romney, whom he views as a flip-flopper and a closet moderate. He says he’s irked because Perry and others are going after Romney on “the one thing he’s actually pretty clearly conservative about.” He directed his ire at both Perry and former House Speaker Newt Gingrich.

“The attacks that they’ve mounted on Romney are indefensible,” Limbaugh said today.
