This temper tantrum from Limbaugh is the biggest sign yet that even the most brainwashed of conservatives can sense that 2012 is starting to slip away from them. Republicans are just starting to grasp that they have nominated a fatally flawed candidate who can’t explain his time at Bain, or even release his own tax returns.

Mitt Romney sold himself to the right as their best chance to beat Obama, but that was never true. Now, Rush Limbaugh is forced to rally the troops by breaking out all of the old lies about the president. Obama is a radical leftist. Obama and Bill Ayers are best buds. Obama is a Chicago style corrupt politician. Obama is a commie because the daddy that he barely knew was one too.

This is all so very 2008.

Limbaugh is running out of defenses for Romney, so he had to double down on the Obama attacks. Like Romney, attacking Obama is all Rush has got. There is still plenty of time left in this campaign, but as long as Romney’s credibility is buried beneath questions about his actions at Bain, finances, and tax returns, he has no chance of getting his message out.
