Fact check: Which states have the highest number of democrat voters vs republican voters?

Checked on September 12, 2025

1. Summary of the results

The analyses provided offer mixed insights into the number of Democrat and Republican voters across different states [1]. According to one source, as of September 2024, there are 45.1 million registered Democrats and 36 million registered Republicans in the US, with California and New York having the highest number of registered Democrats, and Wyoming having the highest percentage of registered Republicans [1]. Another source reports a significant shift of registered voters in Florida towards the Republican party [2]. However, other sources do not provide direct information on the number of Democrat and Republican voters, instead focusing on voting patterns, demographic breakdowns, and voter turnout [3] [4] [5]. A source specific to Utah shows that Republicans have the highest number of registered voters, with 1,022,267 registered Republicans and 282,266 registered Democrats [6].

2. Missing context/alternative viewpoints

A key piece of missing context is the lack of comprehensive data on voter registration across all states, with many sources not providing direct comparisons of Democrat and Republican voter numbers [2] [3] [4] [5]. Additionally, the demographic breakdown of voters and their preferences is not consistently reported across sources, making it difficult to understand the underlying trends [3] [4]. Alternative viewpoints, such as the impact of voter registration shifts on election outcomes, are also not fully explored in the provided analyses [2]. Furthermore, the limits of exit poll data and voter turnout statistics in understanding the broader voter landscape are not explicitly discussed [3] [5]. The source that mentions a Gallup poll finding Democratic identification at a new low of 27% in 2023 does not provide further context on what this means for voter registration numbers [7].

3. Potential misinformation/bias in the original statement

The original statement may be misleading in implying that there is a clear, comprehensive answer to which states have the highest number of Democrat or Republican voters, when in fact, the available data is fragmented and inconsistent [1] [3] [4] [5]. The framing of the question may benefit those looking to simplify complex voter registration trends, potentially oversimplifying the nuances of voter affiliation and registration [2]. Moreover, the lack of discussion on the methodological limitations of the sources, such as the reliance on exit polls or voter registration data, may skew the interpretation of the results [3] [4] [5]. The sources that report a shift towards Republican registration may benefit the Republican party, while the sources that do not provide direct comparisons may benefit those who prefer not to draw attention to specific voter registration trends [2].
