COLUMBIA, S.C. — Jeb Bush dropped out of the presidential race on Saturday, ending a quest for the White House that started with a war chest of $100 million, a famous name and a promise of political civility but concluded with a humbling recognition: In 2016, none of it mattered.
No single candidacy this year fell so short of its original expectations. It began with an aura of inevitability that masked deep problems, from Mr. Bush himself, a clunky candidate in a field of gifted performers, to the rightward drift of the Republican Party since Mr. Bush’s time as a consensus conservative in Florida.
“I’m proud of the campaign that we’ve run to unify our country,” Mr. Bush said, his eyes moist, in an emotional speech here Saturday night after his third straight disappointing finish in the early voting states. “The people of Iowa and New Hampshire and South Carolina have spoken, and I really respect their decision.”
