Limbaugh... Is his star sunk?

Reading this article, Rush Limbaugh challenges President Obama to a debate, I was struck by one, really interesting tidbit:

Only 11% of those under 40 have a favorable view of the talk show host who now claims the mantle of de facto head of the Republican party, according to polling taken last fall.

And that does not bode well for the silver haired, recovering drug addict (still under court control after his arrest for illegally obtaining Oxycontin) and right wing demagogue.
