Nate Cohn: “The battleground in the fight for control of the House is starting to come into focus with 99 days to go until the November election. It’s not exactly the battleground that analysts expected.”

“It’s not dominated by well-educated, suburban districts that voted for Hillary Clinton. Instead, the battleground is broad, and it includes a long list of working-class and rural districts that voted for Donald Trump in 2016.”

“The broader battleground is a positive development for Democrats. It’s a reflection of how much the Republican structural advantage in the House has eroded over the last year. What remains of it isn’t helping the Republicans as much as analysts assumed it would, at least not yet.”
