More than two-thirds of Hispanic voters would cast their ballots for incumbent Barack Obama if the presidential elections were held now, while fewer than a quarter would opt for Republican Mitt Romney, according to a survey released Wednesday.

Over the past two months, more and more Latino voters say they have decided to vote for Obama, from 61 percent in May to 67 percent in July, and those expressing confidence in Romney have fallen from 27 percent to 23 percent, the NBC-Wall Street Journal-Telemundo survey found.
