Pew estimates that 23.7 million Latinos are eligible to vote this year, 11 percent of the overall electorate. And a separate estimate from the National Association of Latino Elected and Appointed Officials projects that a record 12.2 million will vote on Election Day.
But whether that projection will hold true is hard to tell. It's not clear exactly how many eligible Latino voters are registered, but that number has lagged in past elections. And 77 percent of Latino registered voters say they plan to vote, compared to 89 percent of all voters who say the same.
Separate surveys, however, have indicated that Latino enthusiasm about voting is up from earlier this year. And Obama holds a 72-22 percent lead among those who say they are "absolutely certain" to vote, compared to 66-20 percent among those who say they might vote.
One slice of data in an otherwise tough survey that Republicans could take solace in: 71 percent of Latino voters back controversial voter ID laws, only six points lower than the general population.
