RICHMOND, Va. — The American suburbs appear to be in revolt against President Trump after a muscular coalition of college-educated voters and racial and ethnic minorities dealt the Republican Party a thumping rejection on Tuesday and propelled a diverse class of Democrats into office.
From the tax-obsessed suburbs of New York City to high-tech neighborhoods outside Seattle to the sprawling, polyglot developments of Fairfax and Prince William County, Va., voters shunned Republicans up and down the ballot in off-year elections. Leaders in both parties said the elections were an unmistakable alarm bell for Republicans ahead of the 2018 campaign, when the party’s grip on the House of Representatives may hinge on the socially moderate, multiethnic communities near major cities.
“Voters are taking their anger out at the president, and the only way they can do that is by going after Republicans on the ballot,” said Representative Charlie Dent, Republican of Pennsylvania.
The Democrats’ gains signaled deep alienation from the Republican Party among the sort of upscale moderates who were once central to their coalition.
Democrats not only swept Virginia’s statewide races but neared a majority in the House of Delegates, a legislative chamber that was gerrymandered to make the Republican majority virtually unassailable. They seized county executive offices in Westchester and Nassau Counties, N.Y., and carried bellwether mayoral elections in St. Petersburg, Fla., and Manchester, N.H., all races that appeared to favor Republicans only months ago.
