Fact check: What is the current percentage of Democratic voters in California?
Executive Summary
California’s most recent official voter-registration snapshot shows Democrats constitute roughly 45% of registered voters, with the Secretary of State reporting 44.96–45.3% depending on the report date; the variation reflects updates between February and September 2025 and minor counting changes [1] [2]. Claims that Democrats account for “nearly half” of voters are broadly accurate, but precise percentages depend on the specific Report of Registration date cited and on whether one rounds to whole numbers [3] [1].
1. Why the headline numbers differ — reading the official snapshots like a journalist
The primary claims in circulation say Democrats make up either 45.3% or 44.96% of California’s registered voters. These figures come from sequential releases of the California Secretary of State’s Report of Registration: a February 10, 2025 snapshot (45.3%) and a later September 5, 2025 release (44.96%), which lists 10,367,511 registered Democrats as of that September report. Those two official data points explain most headline discrepancies because the state issues periodic registration reports and small changes between them are routine as registrations update and records are corrected [1] [2]. Independent summaries and media accounts describe the Democratic share as “nearly half” of voters, which is a defensible characterization given either figure [3].
2. What the official data actually records — exact numbers and dates matter
The Secretary of State’s reports give precise fractions tied to specific dates: 45.27–45.3% in the February 10, 2025 report and 44.96% in the report reflecting September 5, 2025 registration totals. The February report lists 10,367,321 registered Democrats, while the more recent September report lists 10,367,511, illustrating that absolute counts and percentages can move slightly in opposite directions because total registered-voter denominators change as well. When reporters or analysts summarize the landscape, rounding and which report they cite determine whether they report “about 45%” or “nearly half.” For precision, always quote the percentage and the report date [1] [2] [4].
3. Context beyond the percentage — party shifts and independents matter
Rates alone hide trends: several analyses note the Democratic share declined slightly from earlier years (for example, from ~46% down to the mid-45s between 2021 and 2025), while Republican registration in some summaries rose toward the mid-20% range and No Party Preference or independents remain a substantial bloc (around 20% in some profiles). Those shifts matter for electoral strategy and for how commentators frame statements like “nearly half” — the Democratic lead remains large but is not static. Reporting that focuses only on a single percent risks missing longer-term trends that multiple official releases and policy institutes have tracked [1] [5] [4].
4. How journalists and advocates use the numbers — watch the rounding and framing
Different actors emphasize different framings: media previews of elections often say “nearly half” or “about 50%” to convey scale, whereas party officials and analysts cite exact percentages from a named report to make precise claims. A September 2025 release showing 44.96% can be presented as “just under half” or rounded up to “about 45%,” depending on the speaker’s intent. Such choices are not factual errors but rhetorical moves; readers should check the cited report date and the exact percentage when a speaker’s claim is consequential for claims about competitiveness or mandate strength [2] [3].
5. Reconciling the competing figures — best practices for citing voter registration
When answering “What percentage of California voters are Democrats?” the most defensible approach is to cite the most recent official Report of Registration and its date, note the percentage to two decimal places if available, and mention recent trends. For example: “As of the Secretary of State’s September 5, 2025 report, 44.96% of registered voters were Democrats; earlier February 10, 2025 figures showed 45.3%.” That practice prevents misinterpretation and makes clear that small differences often reflect timing and denominator changes rather than substantive upheaval [2] [1].
6. Bottom line for readers and decision makers — precision and context together
The accurate, evidence-based answer is that Democrats make up approximately 45% of registered voters in California, with official reports ranging from 44.96% to 45.3% depending on the report date. Readers should treat statements rounding to “nearly half” as reasonable shorthand but should insist on a cited report date and exact figure when the difference of a few tenths of a percentage point matters for analysis or policymaking. Claims that stray far from the official reports should be questioned and reconciled against the Secretary of State’s published registration snapshots [2] [1].
