California Voter and Party Profiles

  • Independent registration has increased; four in ten likely voters are Democrats.
    California’s 17.7 million registered voters constitute 72.7% of eligible adults, which is about the same as in 2011 (72.8%), the last year preceding a presidential election. The share of registered voters who are Democrats is down slightly from 2011 (44.0% 2011, 43.2% 2015), while the share of Republicans is down somewhat more (30.9% 2011, 28.0% 2015). At the same time, the share of voters who say they are independent (also known as "decline to state” or "no party preference”) has increased; it is now 23.6%, up from 20.4% in 2011. Our surveys indicate that among those we consider most likely to vote, 43% are Democrats, 32% are Republicans, and 20% are independents.
  • Independent likely voters are split between Democrats and Republicans.
    In our surveys over the past year, independent likely voters were about equally likely to lean Democratic (37%) or Republican (34%); 29% did not lean toward either major party. This marks a shift from 2011, when 35% did not lean toward either party, while 36% leaned toward the Democrats and 29% leaned Republican. Independent likely voters are more likely to be moderate (39%) than conservative (33%) or liberal (28%).
  • Republicans are more ideologically cohesive than Democrats.
    More than two-thirds (69%) of Republican likely voters say they are conservative, while slightly more than half (53%) of Democratic likely voters describe themselves as liberal. One area in which ideological divisions are most evident is taxation and spending: when asked about the role of government, 65% of Democrats say they would prefer to pay higher taxes and have a state government that provides more services, while 77% of Republicans prefer lower taxes and fewer services; independents have a slight preference for lower taxes and fewer services (50% to 43%).
  • Likely voters are disproportionately white; party affiliation varies across racial and ethnic groups.
    Whites make up 43% of California’s adult population, but 60% of those we identified as likely to vote over the past year are white. In contrast, Latinos make up 34% of the state’s adult population but only 18% of likely voters. The shares of Asian (12%) and black (6%) likely voters are roughly proportionate to their shares of the state’s adult population—15% Asian and 6% black. About half (48%) of Democratic likely voters are white; 26% are Latino, 13% are Asian, and 10% are black. An overwhelming majority (80%) of Republican likely voters are white; relatively few are Latino (8%), Asian (8%), or black (1%). Among independents, 55% are white, 19% are Asian, 16% are Latino, and 5% are black.
  • Other demographic characteristics of likely voters also vary across parties.
    Democratic likely voters are more likely to be women (57%) than men (43%), while independents are more likely to be men (56%) than women (44%). Republicans are closely divided (50% men, 50% women). Half of independents (50%) are college graduates, compared to fewer Republicans (39%) and Democrats (38%). About four in 10 Democrats (39%) have household incomes under $40,000, compared to three in 10 independents (29%) and two in 10 Republicans (22%). Independents are more likely to be young adults (18 to 34, 24%) than are Democrats (17%) or Republicans (11%), while Republicans are more likely to be age 55 and older (55%) than are Democrats (49%) or independents (36%).
  • Democrats and Republicans tend to live in different parts of the state.
    The regional distribution of likely voters mirrors that of the state’s overall adult population (27% Los Angeles, 21% San Francisco Bay Area, 17% Orange/San Diego, 17% Central Valley,10% Inland Empire, 9% other counties). Most Democrats live in Los Angeles County (33%) or the San Francisco Bay Area (25%), while most Republicans live in the Central Valley (22%), Orange and San Diego Counties (22%), or Los Angeles County (20%). Independents are most likely to live in Los Angeles County (25%) or the San Francisco Bay Area (24%).
