Romney features Puerto Rico's governor in new Spanish-language ad

Romney has struggled in polls with Latino voters, though Florida's Hispanic communities are culturally and politically distinct from those elsewhere in the United States. This latest ad seems targeted at that state and its large, and fast-growing, Puerto Rican population.

The Romney campaign did not say where the ad is running, but Florida, Colorado, Nevada and Virginia all have large and growing Latino communities, while in the other states the Hispanic populations mostly come from Mexico or Central America. Most of Florida's Hispanic population comes from Puerto Rico, Cuba and elsewhere in the Caribbean and South America.
