Michelle Obama Debuts in Spanish-Language Ad In yet another sign of how important the Hispanic vote is to the Obama campaign, Michelle Obama's first ad is aimed at Latino communities in swing states. In the 30-second spot, Cristina Saralegui, a Cuban-American talk show host, asks the first lady, in Spanish, why it is important for Latinos to vote this year. Subtitles offer a translation of Mrs. Obama's response as she ticks off the president's goal of immigration reform, keeping the health care law and expanding education access. The ad is running on both television and radio in Colorado, Florida, Nevada, Ohio and Virginia. President Obama is relying on Hispanic voters not only to win in those swing states, but also to provide a mandate for his agenda. He told The Des Moines Register on Tuesday that he would pass comprehensive immigration reform. "Should I win a second term," Mr. Obama said, "a big reason I will win a second term is because the Republican nominee and the Republican Party have so alienated the fastest-growing demographic group in the country, the Latino community."
