- Trump endorsed Lieutenant Governor Pamela Evette in the South Carolina Republican governor’s primary over a crowded field that includes two sitting members of Congress
- The South Carolina race follows Trump’s first major statewide primary loss last week in Iowa, where his endorsed candidate was defeated
- Maine’s Democratic Senate primary features frontrunner Graham Platner, whose candidacy has been dogged by a series of recent scandals
What Happened
The South Carolina Republican gubernatorial primary on Tuesday offers another key test of President Donald Trump‘s influence after the president suffered his first major statewide primary loss last week. Trump endorsed Pamela Evette, the sitting lieutenant governor, over the rest of a crowded GOP field that includes state Attorney General Alan Wilson and Representatives Ralph Norman and Nancy Mace in the Palmetto State.
Trump’s endorsement is a powerful factor in a state where Republicans dominate politics. Representatives Mace and Norman, state Attorney General Wilson, and Lieutenant Governor Evette all showcased their proximity to the president. Mace worked for his 2016 campaign, Norman votes with him in the House, Wilson traveled to New York City when Trump was on trial, and Evette hired one of his advisers for her campaign.
The contest is also reprising a bit of 2024 intrigue, with former Governor Nikki Haley endorsing Norman’s bid after the staunch conservative backed her presidential campaign against Trump. Mace has cast the president’s support for Evette as punishment for her push for the Justice Department to release records related to convicted sex offender Jeffrey Epstein.
Also worth watching Tuesday night in South Carolina is Senator Lindsey Graham‘s bid for reelection. Trump participated in a tele-rally Monday night for Graham, a staunch supporter of the president’s war with Iran. Graham faces five opponents, including Mark Lynch, a self-funding businessman who faults Graham for what Lynch describes as out-of-control federal spending. The big question is whether Graham will clear the 50% threshold, or face a runoff.
In Maine, if Democrats want control of the U.S. Senate come November, they almost certainly need to take five-term Republican Senator Susan Collins‘ seat. The outcome of the pivotal race could hinge on whether voters value Collins’ clout and ability to secure federal dollars over Democratic insurgent Graham Platner‘s call to upend a political system he says is rigged against working-class Americans. The first-time Democratic candidate has so far run a barnstorming campaign that already pushed his Democratic rival, Governor Janet Mills, out of the race.
Why It Matters
The South Carolina governor’s race is a critical data point for understanding how much political capital Trump still commands within the Republican Party. His endorsement has been the most valuable commodity in GOP primaries throughout his political career, driving primary voters to back candidates they might otherwise have overlooked. The Iowa loss last week broke that streak in a meaningful way, and a second consecutive defeat — this time in a deeply red Southern state — would sharpen questions about whether Trump’s endorsement power is beginning to erode.
The implications extend well beyond South Carolina. Republicans are navigating a political environment in which Trump will never again appear at the top of a ballot. The party must begin identifying and elevating the next generation of conservative leaders, and the outcome of governor’s races in states like South Carolina will influence who emerges as viable presidential contenders in 2028. A decisive Evette victory could position her as a Trump-aligned figure with a national profile. A loss could empower rivals like Mace, whose political brand is independent-minded conservatism rather than simple loyalty.
Republican primary voters have largely followed Trump’s lead this spring, ousting two senators, a Kentucky congressman, and a handful of Indiana state lawmakers whom Trump had opposed. While Trump remains the most dominant force in Republican politics, his endorsed candidate in last week’s Iowa GOP governor primary — Representative Randy Feenstra — lost to businessman Zach Lahn. That result introduced genuine uncertainty about whether primary voters will follow Trump’s lead unconditionally.
The Maine Senate race carries its own national significance. Collins is one of the most recognizable moderate Republican senators in the country, and her seat is considered a must-win for Democrats in their effort to reclaim Senate control in November. Platner’s ability to consolidate Democratic primary support despite mounting controversies will determine whether the party has a credible challenger ready for the general election fight.
Economic and Global Context
Governor’s races may seem distant from economic policy, but the contest in South Carolina has real downstream economic implications. The state’s next governor will oversee a rapidly growing economy fueled by manufacturing investment, port expansion, and the continued migration of businesses and residents from higher-tax states. The candidates in the Republican primary represent meaningfully different visions of economic governance, with differences on issues including tax policy, regulatory environment, and the state’s relationship with the federal government.
South Carolina has become a manufacturing magnet in recent years, attracting major investments in automotive production, aerospace, and advanced manufacturing. Boeing, BMW, and Volvo all have significant operations in the state. The next governor’s ability to manage labor policy, infrastructure investment, and incentive structures will shape whether that growth trajectory continues. Trump’s endorsement of Evette carries an implicit signal about which candidate he believes best aligns with the pro-business, low-regulation model his administration has championed.
In Maine, the Senate race has significant economic dimensions tied to fisheries, forestry, federal defense contracting, and the ongoing debate over Canadian trade relations. Collins has leveraged her seniority to deliver federal funding for the state, a tangible benefit that any challenger will struggle to match immediately.
Implications
By Tuesday night, the political world will have a clearer picture of Trump’s primary endorsement record heading into the 2026 midterms. An Evette victory — particularly an outright majority avoiding a runoff — would restore confidence in Trump’s political operation and reinforce his grip on the Republican Party. A defeat would invite broader scrutiny of how Trump chooses his endorsees and whether the process is disciplined enough to consistently deliver results.
For the Republican Party apparatus, the primaries in these four states will help clarify which candidates will carry the party’s banner in November’s general elections. Control of governorships and Senate seats is essential for the party’s 2026 midterm strategy, particularly as Democrats are expected to mount aggressive campaigns in competitive states fueled by opposition to the administration’s immigration and foreign policy agenda.
For Trump personally, the political stakes of primary season are high. His fundraising, his influence within the party, and his ability to shape the 2028 presidential landscape all depend in part on maintaining a strong primary endorsement record. Even a handful of high-profile losses could embolden Republican figures who have kept a cautious distance from the president to chart more independent courses.
