In Florida, the Latino vote splits 52 percent for Biden and 39 percent for Trump, among registered voters, an advantage that doesn’t reach statistical significance because of a small sample size. Biden has struggled among some Latino voters, and his campaign has put renewed emphasis on reaching them. In 2016, Hillary Clinton carried Florida’s Latino vote by 62 percent to 35 percent.

In Arizona, Biden leads Trump among Latinos by 61 percent to 34 percent among registered voters. Four years ago, Clinton carried the Latino vote there by 61 percent to 31 percent, according to network exit polls.

The number of Latino likely voters in the two polls is not big enough to break out a separate, statistically reliable finding on the competition between Trump and Biden.

Among White voters, Trump’s candidacy is receiving a boost from those without college degrees. He leads Biden by 30 points (64 percent to 34 percent) among these voters in Florida and by 28 points (62 percent to 34 percent) in Arizona. A narrowing of that advantage in Rust Belt states has helped Biden.
