The Obama campaign released a Spanish-language TV ad, "Dos Caras," which accuses John McCain of being two-faced when it comes to Latino voters. The ad associates McCain with harsh anti-immigrant comments made by Rush Limbaugh. The ad will air in the closely contested swing states of Colorado, New Mexico, and Nevada, all of which have large Hispanic populations. On the day the ad was released, McCain made a gaffe with the Hispanic press by not expressing support for the Prime Minister of Spain.

Spanish-language ads have been used in many elections since 1960, when Jackie Kennedy appeared in the ad below.
