NYT‘s “The Tilt:”

The early polls show Donald J. Trump and President Biden tied nationwide. Does that mean Mr. Trump has a clear advantage in the battleground states that decide the Electoral College?

It’s a reasonable question, and one I see quite often. In his first two presidential campaigns, Mr. Trump fared far better in the battleground states than he did nationwide, allowing him to win the presidency while losing the national vote in 2016 and nearly doing it again in 2020.

But there’s a case that his Electoral College advantage has faded. In the midterm elections last fall, Democrats fared about the same in the crucial battleground states as they did nationwide. And over the last year, state polls and a compilation of New York Times/Siena College surveys have shown Mr. Biden running as well or better in the battlegrounds as nationwide, with the results by state broadly mirroring the midterms.

The patterns in recent polling and election results are consistent with the trends in national surveys, which suggest that the demographic foundations of Mr. Trump’s Electoral College advantage might be fading. He’s faring unusually well among nonwhite voters, who represent a larger share of the electorate in noncompetitive than competitive states.
