Just shy of a quarter of the state’s voters now forgo any party label, registering as “no party preference,” a slight increase from last year. If the trend continues, as expected, California’s pool of independent voters could soon surpass the number of Republicans in the state.

Democrats account for 45% of California’s registered voters, giving the party a 19 percentage point advantage over the GOP, the state registration figures show.

The Democratic Party’s slice of the electorate in non-presidential election cycles has remained relatively stagnant for two decades, while the Republican Party’s registration slipped by 10 percentage points.
