Older white voters: We used Civiqs data back in late April to look at this trend, but the New York Times had a fresh look over the weekend.
White non-college educated women: Here's Civiqs data, and here's the Washington Post on the trend.
Suburban women: Actually not new, suburban women turning against Trump and Republicans in sizable numbers was the story of the 2018 midterms and nothing has changed since then.
Suburban everyone: What is new-ish is that Trump is repelling pretty much all suburban voters, white-collar voters. CNN, Politico, Post, U.S. News and World Report.
White voters: Post and NYT.
Swing voters: NYT and Axios.
Of course, none of this assures Democratic success in November, but it sure makes Trump's path to reelection nearly unimaginable at this point. Given that he won the Electoral College in 2016 with just 46% of the vote, once he loses a point here and a point there, the math becomes nearly impossible.
At this rate, Trump's going to be down to white supremacists and neo-Nazis by November and that's about it. That may be a deeply loyal coalition, but sorry, that's not a winning coalition.
