Since a poll conducted April 6-12, the week that Sen. Bernie Sanders (I-Vt.) dropped out of the Democratic presidential race, Biden has improved by double digits among black voters ages 30-44 and Gen Z Hispanic voters, ages 18-21. He has also made notable improvements among Hispanic men, black men and Hispanic or black self-described liberals. Along with increases in support among white men ages 18-29, Biden appears to be consolidating the kind of voters who favored Sanders during the primary.

Among the more than 200 demographic groups detailed in the survey, Trump made statistically significant headway with just one population: Hispanic voters ages 65 and older, though Biden still leads among the group by 12 points, 52 percent to 40 percent. And while Biden trailed Trump among white voters in that April survey by 8 points, 40 percent to 48 percent, the latest poll found him within 3 points, 42 percent to 45 percent, with the group that backed Trump with 57 percent of the vote in 2016, according to exit polls.
