California Gov. Gavin Newsom (D) has built a fundraising effort that mirrors those of presidential candidates, as Democrats begin to wonder whether they should drop the aging, legally vulnerable incumbent President Joe Biden from the 2024 election ticket.

A year ago, Newsom told the White House that he would not run in 2024 — at least not to challenge Biden and Vice President Kamala Harris, who is from his home state of California and his home city of San Francisco. But circumstances have changed.

Biden’s age is showing; his polls are dismal, despite positive economic signs; and he may even face an impeachment inquiry as evidence emerges that he was part of a lucrative influence-peddling scheme using his son as a go-between to foreign businesses.

Forming the trio of fundraising committees allows prospective candidates like Newsom to begin building a base of support and explore a run for federal office without saying it outright, according to Brendan Glavin, senior data analyst at Open Secrets.

“For someone who has an interest in launching a presidential campaign, these are the first steps you’d take,” Glavin said. “I wouldn’t say it’s set in stone, but certainly you wouldn’t do all of these things if you weren’t thinking about it.”
