PALM BEACH, Florida/HUNTINGTON BEACH, California — President Joseph R. Biden and former President Donald Trump swept to victory in statewide nominating contests across the country on Tuesday, setting up a historic rematch in November’s general election despite low approval ratings for both candidates.
Mr. Trump won the Republican votes in a dozen states — including delegate-rich California and Texas — brushing aside former UN Ambassador Nikki Haley, his lone remaining rival, whose campaign no longer has a viable path to the nomination. Her only win of the night thus far came in Vermont, Edison Research projected.
After a commanding performance across 15 states where more than one-third of Republican delegates were up for grabs on Super Tuesday, Mr. Trump had all but clinched his third consecutive presidential nomination, despite facing a litany of criminal charges.
Mr. Trump and Mr. Biden trained their focus on each other as the results became clear. In a victory speech delivered at his Mar-A-Lago estate in Florida, Mr. Trump attacked Mr. Biden’s immigration policies and called him the “worst president” in history.
“November 5th is going to go down as the single most important day in the history of our country,” Mr. Trump said.
In a statement, Mr. Biden again cast Mr. Trump as a threat to American democracy. “Tonight’s results leave the American people with a clear choice: Are we going to keep moving forward or will we allow Donald Trump to drag us backwards into the chaos, division, and darkness that defined his term in office?” Mr. Biden said.
Mr. Biden had been expected to sail through the Democratic contests, though a protest vote in Minnesota organized by activists opposed to his forceful support of Israel attracted unexpectedly strong results.
The “uncommitted” vote in Minnesota stood at nearly 20% with more than half the estimated vote counted, according to Edison, higher even than the 13% that a similar effort in Michigan drew last week. Mr. Biden nevertheless won Minnesota and 14 other states, including a mail-in vote in Iowa that ended on Tuesday.
He did suffer one loss, in the US territory of American Samoa’s caucus, where entrepreneur Jason Palmer won 51 votes to Mr. Biden’s 40, according to the American Samoa Democratic Party.
Another campaign between Mr. Trump, 77, and Mr. Biden, 81 — the first repeat US presidential matchup since 1956 – is one few Americans seem to want. Opinion polls show both Biden and Trump have low approval ratings among voters.
Immigration and the economy were leading concerns for Republican voters, Edison exit polls in California, North Carolina and Virginia showed. A majority of Republican voters in those states said they backed deporting illegal immigrants. Mr. Trump, who frequently denigrates migrants, has promised to mount the largest deportation effort in US history if elected.
Katherine Meredith, a 65-year-old homemaker, voted for Mr. Trump in California’s Huntington Beach.
“The border is a complete catastrophe,” she said.
WEAKNESSESVoters were also casting ballots in down-ticket races, including a contest in California to identify potential successors to the late Democratic US Senator Dianne Feinstein.
In Arizona, independent US Senator Kyrsten Sinema, a former Democrat, said she would not run for reelection, setting up a battle for her seat that could determine control of the closely divided Senate next year.
In North Carolina, Trump-endorsed Lieutenant Governor Mark Robinson won the Republican nomination for governor. Robinson, who would be the state’s first Black executive, has drawn criticism for harsh comments about LGBTQ people, women and Muslims.
He will face Democratic Attorney General Josh Stein in what will be one of the most hotly contested governor races in the country.
Pop megastar Taylor Swift encouraged her fans to vote in a post on Instagram, though she did not endorse specific candidates. Mr. Biden’s campaign is hopeful Ms. Swift will eventually back his candidacy, as she did in 2020.
Ms. Haley’s challenge has highlighted some of Mr. Trump’s potential general election vulnerabilities. She has reached 40% in some state contests, performing particularly well among independent, well-educated and suburban voters who could play a crucial role in battleground states in November.
About one-third of North Carolina voters said Mr. Trump would not be fit to serve as president if he was convicted of a crime, while in Virginia, 53% said he would be fit for the office if convicted.
Mr. Trump is scheduled to begin his first criminal trial on March 25 in New York, where he is charged with falsifying business records to conceal hush money payments to a porn star during his 2016 presidential run.
In addition to the New York case, Mr. Trump faces separate federal and Georgia state charges for election interference, though it is unclear whether either case will reach trial before November’s election. He also faces federal charges for retaining classified documents after leaving office.
Mr. Trump has pleaded not guilty in all four criminal cases.
Mr. Biden faces his own weaknesses, including widespread concern about his age. He is already the oldest US president in history. — Reuters
