Backing a scandal-hit candidate in deep-blue California could hand Republicans the governor's mansion, which would be a major loss for Democrats.

• Establishment Democrats like Jasmine Crockett and Jim Clyburn are backing Ami Bera for California governor.
• Bera's chief of staff and campaign manager took money from his account improperly, and the campaign manager has already pleaded guilty.
• If Bera wins the primary against Republican Steve Hilton, the corruption case could cost Democrats the seat.
• Tom Steyer is the cleaner option, running on anti-corruption and a plan to push money out of California politics by threatening corporate charters.
• The pattern looks like Democrats picking a corporate candidate with legal risk over a stronger general-election bet.

Outlook: If Bera wins the Democratic primary, California's governor race becomes unexpectedly competitive for Republicans.
