Is Rush Limbaugh insane or back on drugs?

When you do same thing over and over again and expect a different result that's insanity.That's what the yahoos on Right do all the time,close the government brilliant the public hates it but Limbaugh and company wants the G.O.P to be suicide mission.Fight,fight,fight that's the motto but didn't work out so well in "The Charge of the Light Brigade."
