Just out today from Pew Research:
In the presidential contest, Donald Trump faces a 10 percentage point deficit in his race against Joe Biden: 54% of registered voters say if the election were held today, they would support Biden or lean toward voting for him, while 44% support Trump or lean toward supporting him.
By well more than two-to-one (68% to 28%), voters ages 18 to 29 favor Biden over Trump. Biden also has a wide advantage (60% to 38%) among registered voters ages 30 to 49. Comparable shares of voters 50 and older say, if the election were today, they would support Trump (51%) and Biden (47%).
Nearly two-thirds (64%) of voters with postgraduate experience say they would vote for Biden. The same share of those with a four-year degree also support Biden. Among voters with some college experience or no college experience, neither candidate has an advantage.
