But the Democrats failed to unite behind a single candidate.
Elevated Democratic turnout and machinations by party leaders to steer voters toward candidates they think had the best shot of winning, in some cases by badgering others to drop out of the race, allowed the party to avoid disaster.
That was alarming because flipping at least a few seats in California would be critical to Democratic hopes of retaking control of the House this year and making life miserable for Trump, perhaps even launching impeachment proceedings against him.
