Race To The Bottom.

From Politico.com:

     Rush Limbaugh, featured in a new, Spanish-language Barack Obama ad, says the commercial distorts his past statements and amounts to "race-baiting" by the Democratic nominee.
     The commercial, to air in Limbaugh's home state of Florida as well as Colorado, New Mexico and Nevada, features a picture of the conservative talk show host and shows his words on the screen: "Mexicans are stupid and unqualified" and "Shut your mouth or get out."  It was first reported by the Washington Post's Ed O'Keefe.
     "Obama is now stoking racism in the country," Limbaugh wrote in an email.  "Obama is a disgrace - he wants the public to think he is Mr. Nice Guy while his thugs are in Alaska looking for dirt on Palin and he runs race-baiting ads and lies about what he has done and what McCain has done."

     From 2007 in The Nation:

     Rush Limbaugh has obviously learned nothing from the outrage and anger unleashed by Don Imus' unfortunate "nappy headed ho's" remark. Never one to shy away from unfunny "humor", Limbaugh recently played a song parody on his radio show in which an Al Sharpton impersonator (played with stereotypical gusto) sings a song filled with idiotic assumptions about black people and dripping with ignorance called "Barack the Magic Negro".

     The list of racist, sexist, and just plain stupid shit beamed from Rash Limbo's microphone to his fact-challenged sheep would stretch from Wasilla to Washington...

     It takes a whole lotta Oxy to make that trek.
