This is evidenced by the fact that The National Review listed "Rock the Casbah" as Number 20 on their list of the Top 50 Conservative Rock Songs:

Likely he would listen to The Clash CDs while waiting in the car as his housekeeper was in the back kitchen of a Denny's trying to score a load of Oxycodone on his behalf.
Given then The Clash often preached messages of challenging authority, The Clash likely inspired Limbaugh to make his recent statements where he desires President Barack Obama to fail.
Thanks a lot, The Clash! You just inspired a fat pill-popping blowhard to desire the President to fail in his attempts to bring economic stability back to the country and as a result have this country fall into a deep depression. I hope you're all proud.
