LOS ANGELES (AP) — Seven candidates who want to be California’s next governor traded sharp attacks Tuesday in a wide-ranging debate that touched on issues from gas prices to raising taxes to healthcare in a contest that has no clear leader.

The televised debate came as mail voting was already underway in advance of a primary election that ends June 2. It was clear from the testy tone that candidates viewed the matchup as a critical juncture, with a national audience watching as it aired on CNN. The candidates are vying to replace Democratic Gov. Gavin Newsom, who is barred by law from seeking a third term, to lead the nation’s most populous state and one of the world’s largest economies.

During the two-hour showdown, Republicans Steve Hilton, a conservative commentator, and Riverside County Sheriff Chad Bianco said Democrats have made life worse for California’s nearly 40 million residents during more than 15 years in the governor’s office and that it’s time for a change.

The Democrats — former state Attorney General Xavier Becerra, former U.S. Rep. Katie Porter,billionaire Tom Steyer, San Jose Mayor Matt Mahan and former Los Angeles Mayor Antonio Villaraigosa — tried to distinguish themselves on policy and said President Donald Trump is California’s biggest threat.
