An ebullient President Biden said he’s “not going anywhere” and that “Motown is Joe-town” as he courted Michigan voters late Friday, reaching truly comfortable terrain for the first time in three weeks after a disastrous debate performance raised doubts his candidacy.

“You the voters, you decided. And I’m not going anywhere,” he told a raucous crowd.

As an increasing chorus of Democrats in Congress call for his ouster from the ticket, Mr. Biden basked in the vocal support of the warm crowd in Detroit, the largest city in Michigan.

“Don’t you quit! Don’t you quit!” the crowd shouted.

While there are doubts in the Democratic Party, “there are still plenty of us who fully support our president,” said Pastor Cindy Rudolph, who introduced the president.

Taking the stage, Mr. Biden gave them what they wanted.

“I am running and I’m gonna win,” he said. “Donald Trump is a loser.”

For days Mr. Biden, 81, has insisted he will stay in the presidential race despite the turmoil sparked by his poor debate performance against Mr. Trump on June 27.

Michigan is a swing-state prize. It doles out 15 electoral votes.

Before his rally, Mr. Biden vowed to “finish the job” and made jokes about his age during a stop at Garage Grill and Fuel Bar in Northville, Michigan, to greet local supporters and volunteers.

“We were told we were going to lose in 2020. Remember? Well, we won,” Mr. Biden said.

The media, he said, “Say I’m naive, even though I’ve been around 270 years.”

Despite his confidence, Mr. Biden faces significant headwinds. Polls show majorities of Americans want him to step aside and let Vice President Kamala Harris or an alternative Democrat helm the ticket, citing doubts about his age and faculties.

Some congressional Democrats have rallied behind the president, yet his prospects dimmed when former House Speaker Nancy Pelosi this week said it is up to Mr. Biden to decide his future, which was hardly an endorsement.

Actor George Clooney, who recently held a fundraiser for Mr. Biden, penned a cutting op-ed that called the president a dear friend but urged him to step aside for the good of the country.

Republicans ridiculed Mr. Biden ahead of his visit to Michigan, pointing to a Democratic lawmaker from the swing state who called on him to step down.

“Joe Biden is so unpopular that members of his own party want him out of the race – even Democrat Congresswoman Hillary Scholten thinks Biden is unfit to run the country,” Republican National Committee Chairman Michael Whatley said.
