Gavin Newsom is having a moment. In the national struggle over U.S. House control, perhaps no politician has more at stake than the California governor, who has emerged as the leading Democratic adversary to President Donald Trump in what many see as a lightly masked trial run for his own future White House bid.

Governor Newsom signed his redistricting proposal, allowing Californians to vote on congressional maps.

The incredibly condensed timeline to persuade voters is further compressed by the state’s reliance on mail-in ballots, which will arrive in the hands of voters in just over a month.
