You can see that in almost every demographic category, Trump’s share of the vote mirrors what he got in 2016. In other words, there’s no evidence that he’s slipped significantly with his base, or gained support from anyone who didn’t support him in 2016.

For example, for all the talk of Trump’s cratering in the suburbs, the recent Pew poll finds that the president isn’t doing any worse today among white, college-educated voters than he did in 2016. In 2016, Trump took just 38 percent of the vote from this group. Today, he’s still sitting at 38 percent. But, Biden has improved on Hillary Clinton’s 55 percent showing by 6 points to 61 percent. Trump hasn’t lost support from his core white, non-college base either. The July/August poll found him taking 64 percent with this group — the same percentage he got in 2016. But, Biden has improved on Clinton’s anemic 28 percent showing by 6 points. Most important, Trump has made no gains among independent voters, while Biden has improved on Clinton’s showing by 14 points.

One bright spot for Trump is an increase in support from Latinos. He took 35 percent of the vote among Hispanics in July/August, a 7 point increase from his 2016 showing. His support among Evangelical Protestants has also improved — from 77 percent in 2016, to 83 percent.
