LOS ANGELES (MCT) — President Barack Obama’s advantage among Latino voters is getting larger, a new poll suggests, even as Mitt Romney’s campaign released what it said was its ninth ad in Spanish.

The poll by Latino Decisions, released Wednesday, showed support for Obama rising to 70 percent of registered Latino voters, compared with 22 percent for Romney. If that margin held until the election, it could play a significant role in battleground states with sizable Latino populations, such as Florida, Nevada and Colorado.
