This chart shows why Trump is *so* dangerous to the GOP

The chart above — from Ford Fessenden and Lazaro Gamio, two talented data journalists, for The New York Times — makes that point in the starkest and most powerful way I have yet seen.

The exit poll from that year tells the story. Trump won Whites with a college degree (or higher) by 3 points over Hillary Clinton. He won Whites without a college degree by 37 points. The former group made up 37% of the overall electorate while the latter was 34%.

The effects of such a base-centric campaign was evident in the 2018 midterms where Republicans suffered widespread losses as suburban voters — particularly women — rebelled against the brand of conservatism Trump was selling.

Republican House candidates lost White voters with college degrees in that election by 8 points and won White, non-college voters by 24 — a double-digit drop from Trump’s 2016 margin.

Now take a look at the chart above again. What Trump has done over the past four years is make himself — and the GOP — extremely popular among a group of voters whose numbers (as a percentage of the total electorate) have almost been cut in half over the past three decades.

At the same time, Trump’s presidency has driven away growing segments of the electorate. White college-educated voters have doubled as a percentage of the electorate since 1976 while minority voters have nearly tripled.

Those numbers, taken as a whole, should serve as a bright, blinking alarm for Republicans in office and those who want to be in office in 2022, 2024 and beyond.

The country isn’t getting any Whiter. Or less educated. Which means that even if Trump can cobble together enough of his shrinking coalition in 2020, it’s going to be very, very difficult for Republicans to follow in his footsteps beyond November.

The Point: Demographics are political destiny. Even if Donald Trump doesn’t believe it.
