Did under-reporting of Latino vote skew the polls?

Could under-reporting of the Latino vote have skewed political polls this year? That’s a real possibility, Nate Silverconcludes at FiveThirtyEight.com. Results from 15 statewide races in states with the largest proportion of Hispanics in the population showed that Democrats–who tend to be more heavily-favored by Latino voters–did better than projected in 10 of them.

In Connecticut, Hispanics comprise 8.2 percent of eligible voters, according to the Pew Hispanic Center, ranking 11th among the states. And in the hotly-contested 4th and 5th Congressional districts, where the Democratic incumbents outperformed the polls, the proportion is higher than that.
