NYT:

Over the past four months, Gavin Newsom, the Democratic governor of California, has traveled to six Republican-led states. He has goaded Gov. Ron DeSantis, the Republican presidential candidate from Florida, to debate on Fox News. He has assembled a small staff of political advisers and created a political action committee to distribute $10 million to Democratic causes and candidates.

And this week, he raised $40,000 for a long-shot candidate for the United States Senate in Tennessee, one of the red states he has criticized his own party for neglecting.

By all appearances, Mr. Newsom is a man with an eye on the White House, building a national network of supporters and accumulating the kind of good will among donors, party operatives and voters that could prove critical should he decide to move beyond Sacramento. Mr. Newsom said in an interview that he was not running for president, and that the time has come for Democrats to rally around President Biden.

“The train has left the station,” Mr. Newsom said. “We’re all in. Stop talking. He’s not going anywhere. It’s time for all of us to get on the train and buck up.”
