Barack Obama is airing this new ad, “Dos Caras” (“Two Faces”) in heavily Latino media markets in the Southeast U.\S. The ad’s ominous Spanish-language voiceover ties John McCain to Rush Limbaugh and George Bush, saying,

They want us to forget the insults we’ve put up with, the intolerance. They made us feel marginalized in a country we love so much. John McCain and his Republican friends have two faces. One tells lies just to get our vote, and the other, even worse, continues the failed policies of George Bush, putting the interests of powerful groups above working families. John McCain, more of the same Republican deceptions.

Though the voiceover is standard-issue Democratic rhetoric, Newsweek‘s Andrew Romano and other analysts are calling this new ad unfair, pointing to the screen shot of Rush Limbaugh, with racist Limbaugh quotes in text below (“Mexicans are stupid and unqualified” and “Shut your mouth or get out”).

Limbaugh actually opposed McCain in the Republican primary, because of the Senator’s former support of “amnesty” for illegal immigrants. Though McCain recently changed his mind about comprehensive immigration reform, saying in a debate that he would vote against his own bill if it were to come up again, he still won the ire of many on the far right for championing such a cause in the first place.

Stay tuned for McCain’s response.
