Trump Touts 98% Endorsement Win Rate in Republican Primaries Since 2018
Trump shares a scorecard claiming 693 of 709 endorsed candidates won GOP primaries across five election cycles, with U.S. Senate races topping the list at 99%.
WASHINGTON D.C. — Donald J. Trump claimed a 98% success rate for his Republican primary endorsements, saying his picks won 693 of 709 contested races since 2018.
The scorecard he posted breaks the record down by office, crediting his U.S. Senate endorsements with a 99% win rate, his U.S. House picks with 98% and his gubernatorial choices with 88%. The figures span five cycles from 2018 through 2026, with the strongest single-year mark reaching 99% in the 2026 primaries.
Here is the full post on truthsocial: “Endorsement Record in Republican Primaries Record by Office | 2018 – 2026 OFFICE TOTAL U.S. Senate U.S. House Governor CYCLE TOTAL” on August 4, 2026 at 5:49 PM ET.
This is Trump’s 12th message released today, and the last post arrived minutes ago, and it is not part of a thread. On average, Trump produces 18 posts per day since his inauguration on January 20, 2025. The move fits a broader pattern in Trump’s recent messaging, with 88 of his 415 posts over the last 30 days classified as Elections posts.
The post arrived as an infographic rather than a text statement. The chart uses green circular progress rings to display win-loss ratios for each office and cycle. The 2026 column shows Senate endorsements at 100% on 17 of 17 races, House endorsements at 100% on 154 of 154 races and gubernatorial endorsements at 86% on 12 of 14 races.
The stakes reach beyond a personal record. A high endorsement win rate strengthens Trump’s leverage over candidates seeking his backing, since primary voters treat his support as a decisive signal. Candidates who win his nod gain fundraising momentum and national attention, while rivals who lose it often struggle to compete. Party officials and donors read the same numbers when deciding where to spend.

Endorsements have anchored Trump’s grip on the Republican Party since he left the White House. The scorecard credits his weakest office category, governors, with 45 wins in 51 races, an 88% rate. His House endorsements carried 556 wins in 565 races. The 2024 Senate column marks the only sub-95% Senate figure on the board at 94%, or 17 of 18 races.
For the average reader, primary endorsements shape which candidates appear on the general-election ballot. A voter in a heavily Republican district may find that the primary, not November, decides the seat. Trump’s influence over those primaries can therefore determine who represents millions of Americans in Congress and in statehouses.
This is not the first time Trump has publicized his endorsement scorekeeping. He has cited high win rates before each midterm and presidential cycle to press candidates for loyalty and to warn primary challengers away from incumbents he favors.
The next test of these figures will come in the 2028 primary calendar, though no specific races or dates tied to fresh endorsements have been announced.
Party leaders have long treated endorsements as currency. Franklin D. Roosevelt tried to purge conservative Democrats in the 1938 primaries by campaigning against sitting senators, yet nearly all of his targets survived and returned to Washington. The failed effort weakened his standing with Congress and showed that even a sitting president cannot always bend a primary electorate to his will.
