The districts with college-educated women that voted Republicans out

Here's a big part of the reason House Republicans lost the suburbs in the midterms: They were thrown out in 16 districts where at least 40% of the women have college degrees.

Why it matters: It means the gender gap and the education gap are combining into a huge demographic problem for Republicans. Per lobbyist Bruce Mehlman, who highlighted the shift in his slide deck on the midterms: "The new geography of Trump Era partisanship is turning suburban congressional districts into GOP killing fields, more than offsetting gerrymander gains by mobilizing intense opposition among college educated women, the beating heart of the suburbs."

Editor's note: This graphic has been updated to show that the California 45th district seat flipped to the Democrats. It has also been corrected to show that the Kansas 3rd district seat flipped to the Democrats and the Texas 21st and 3rd districts seats were won by the Republicans.
