Fact check: How many registered voted for Trump, Harris, 3rd party candidates in the 2024 election? How many registered voters did not vote at all in that same election?

1. Why the headline numbers don’t answer the voter-by-candidate question

National reporting and census tables provide total ballots cast and turnout rates, but do not directly report how many registered voters specifically chose each presidential candidate. The Census Bureau’s post-election tables give registration and turnout percentages—for example, 73.6% registered and 65.3% turnout of the citizen voting-age population—but these are population-level measures and do not translate into a certified count of registered voters by candidate ^[3]. Other contemporary reporting rounds these aggregates into totals such as “about 155 million ballots cast” and estimates of non-voters, yet they stop short of the precise registration-to-candidate mapping the original question requests ^[4].

2. What the sources do say about turnout and abstention

Multiple pieces summarized here converge on the scale of participation and abstention: approximately 155 million ballots were cast in the 2024 general election, and analysts estimate that roughly 89 million eligible Americans did not vote, representing about 36% of the voting-eligible population, a figure that outnumbers votes for any single major candidate under these summaries ^{[4] [5]}. The Census Bureau’s registration and turnout tables dated April 30, 2025, are the most systematic source cited for registration and turnout percentages, reporting 73.6% registered and 65.3% voting among the citizen voting-age population; these percentages form the basis for converting population counts into aggregate participation figures ^[3].

3. What’s missing: registered-voter counts by candidate

None of the supplied analyses provide a national certified count of registered voters who voted for Trump, Harris, or third-party candidates; the articles either discuss turnout patterns, third-party effects, or offer anecdotal reasons for abstention without offering an aggregate registered-voter-by-candidate table ^{[1] [2] [5]}. The JavaScript/website artifact referenced explicitly lacks substantive election results, and several pieces note that third-party dynamics affected margins but again provide no hard registered-voter tallies by candidate ^{[6] [2]}. This gap prevents a definitive numeric answer from these sources alone.

4. Reconciling the partial facts: ballots, winners, and third-party influence

From the available materials one can confidently state that Donald Trump won the 2024 popular vote in the sources that report results, and that third-party candidacies were discussed as potentially drawing votes from front-runners, but these reports do not quantify precisely how many registered voters cast ballots for each named candidate ^{[4] [2]}. Analysts and journalists described turnout dynamics and third-party vote splitting qualitatively; the research and census tables provide the macro denominators—registered population and total ballots—but not the micro numerator of registered-voter choice per candidate ^{[1] [3]}.

5. How to obtain the specific registered-voter-by-candidate counts the question seeks

To compile the requested breakdown—registered voters who voted for Trump, Harris, third-party candidates, and registered non-voters—you would need to aggregate state-certified vote totals and state voter registration databases and reconcile them with national registration aggregates; the sources reviewed indicate that such a reconciliation is not present in the cited materials and must be assembled from state certification reports and the Census registration tables ^{[3] [4]}. The current sources recommend relying on official state canvass documents and the aggregated federal statistics to produce the per-candidate registered-voter totals, but they do not themselves perform that aggregation ^{[1] [3]}.

6. Diverging narratives and potential agendas in the coverage

Coverage focused on turnout and third-party effects often emphasizes political implications—who benefited or lost—rather than administrative tabulations, creating a narrative gap between electoral analysis and raw registration-to-vote accounting ^{[2] [5]}. Some pieces highlight the political angle of third-party voters and ranked-choice preferences, while Census-oriented reporting focuses on demographic turnout patterns; these different agendas explain why none of the sampled sources provide the exact registered-voter-by-candidate figures requested ^{[6] [2] [3]}.

7. Bottom line and next steps for a definitive answer

Based on the provided materials, a precise national count of registered voters who voted for Trump, Harris, third-party candidates, and registered non-voters is not directly available; the best concrete figures the sources offer are ~155 million ballots cast and an estimated ~89 million non-voters, with 65.3% turnout among the citizen voting-age population per Census tables ^{[4] [3] [5]}. To produce the breakdown you asked for, compile state-certified vote totals and official state registration rolls and reconcile them with the Census registration data; the reviewed sources point to these official records as the missing pieces but do not themselves provide the final per-candidate registered-voter counts ^{[1] [3]}.
