A group of liberal senators is quietly challenging the minority leader over his approach to the midterms and President Trump, in a sign of the party’s deep frustration.

As the president forced a onetime loyalist from Congress, her defiant departure signaled a coming debate over Republican identity in a post-Trump era.

Victories in New York City, New Jersey, Virginia and elsewhere were decisive, but new political tests loom for a party still rebuilding its brand.

Casting around for culprits, leaders in the party blamed their candidates, the government shutdown and a weak economic message.

While other Democrats have tried to address their party’s failings with new strategies, Abigail Spanberger in Virginia and Mikie Sherrill in New Jersey are hoping to once again tap into anger at the president.

As Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez joined Zohran Mamdani on Sunday at Forest Hills Stadium, a bigger test for the left may still lie ahead.

Ms. Harris, in an interview with the BBC, gave her strongest indication yet that she was thinking about making another bid for the Oval Office.

Andrew Cuomo attacked Zohran Mamdani after 650 rabbis said Mr. Mamdani’s election would threaten Jews’ safety. Mr. Mamdani said he was being criticized because he could become the city’s first Muslim mayor.

Democrats are battling each other over age, with the nation’s oldest president in office.

Zohran Mamdani is stepping up his Jewish outreach, as he holds private meetings with rabbis and other leaders across New York City who oppose his stance on Israel.
