Trump’s Endorsement Power Remains Strong as New Survey Reveals Deep Divide Within GOP Voters

Trump continues to maintain a strong influence over Republican voters, especially those aligned with the MAGA movement, according to a recent national survey conducted by the Marquette Law School. The findings highlight how former President Donald Trump’s political endorsements still play a decisive role in shaping Republican primary choices across the United States.
The survey data shows that a large majority of Republican voters remain strongly responsive to Trump’s political backing. Around 71% of Republicans said they would support a GOP candidate endorsed by Trump in a primary race. In contrast, only 20% of respondents indicated they would choose a Republican candidate who had been opposed by Trump. These results suggest that Trump’s endorsement continues to be a powerful factor in Republican primary politics.
The influence becomes even more pronounced among voters who identify with the MAGA movement. According to the survey, 87% of MAGA-supporting Republicans said they would vote for a candidate endorsed by Trump. Only a very small share, about 9%, said they would back a Republican candidate who had been rejected by him. This data reflects a strong alignment between MAGA voters and Trump’s political preferences.
However, the survey also highlights a clear divide within the Republican Party. Among Republicans who do not view the MAGA movement favorably, support for Trump-backed candidates drops significantly. In this group, only 30% said they would vote for a candidate endorsed by Trump, while 48% preferred a candidate opposed by him. Another 22% said they would not participate in such a hypothetical primary contest. This split indicates that Trump’s influence is not uniform across the entire Republican base.
The poll also measured Trump’s approval ratings among different voter groups. Among MAGA-aligned Republicans, Trump’s job approval rating remains extremely high at 93%, showing strong satisfaction with his leadership. In contrast, among Republicans who are not supportive of MAGA, his approval rating falls sharply to 36%, reflecting growing ideological differences within the party.
Overall, across all respondents, Trump’s approval rating stands at 38%, while 62% expressed disapproval. These figures point to a broader national polarization surrounding Trump’s political role and influence.
The survey was conducted between May 20 and May 26 and included responses from 1,001 U.S. adults. The margin of error is approximately 3.4 percentage points for the overall sample and 5.3 percentage points among Republican respondents.
The results come at a time when Trump-endorsed candidates have recently seen notable success in several state-level Republican races, including contests in states such as Indiana, Louisiana, Kentucky, and Texas. These outcomes further reinforce the survey’s findings that Trump remains a central figure in shaping Republican primary outcomes.
Overall, the data suggests that while Donald Trump’s influence remains highly strong within the MAGA base and Republican primaries, it also exposes a growing divide within the party, where support is increasingly split along ideological lines.
