As Wisconsin voters head to the polls today, the broader picture of the 2026 primary season is coming into focus β and it’s a brutal one for incumbents. According to American Thinker’s Silvio Canto Jr., this is shaping up to be “the year of the primary,” a cycle in which sitting members of Congress are discovering that their seats are far less secure than they once assumed.
The numbers are striking. Nine sitting U.S. House members have already lost their primaries, and the count may not be finished. More than a dozen states have yet to vote, meaning the final tally could climb higher.
A record-breaking wave of incumbent defeats
Tennessee Republican Andy Ogles became the ninth House incumbent to fall when former state Agriculture Commissioner Charlie Hatcher defeated him by roughly 53 percent to 47 percent on Thursday night. That victory pushed the 2026 incumbent casualty count to six Democrats and three Republicans β the largest number of House primary defeats in a year without nationwide redistricting since 1970, according to figures NBC News compiled from Vital Statistics on Congress.
The fact that this is happening in a non-redistricting year makes the wave all the more significant. Redistricting years often produce more primary challenges simply because new district lines create uncertainty. But 2026 is different. The losses are driven not by map changes but by voters’ mood β and, in particular, by their feelings about one man: former President Donald Trump.
Two parties, one test: Trump
Even though Trump is not on the ballot this year, his shadow looms over nearly every contested primary. On both sides, a candidate’s relationship with Trump has become the single most determinative factor β albeit in opposite directions.
Among Republicans, the common denominator is friction with Trump. Candidates who have appeared insufficiently loyal, or too willing to distance themselves, have found themselves vulnerable. The most prominent example came in Texas, where Senator John Cornyn was defeated by Attorney General Ken Paxton. Why? Because, as Canto puts it, many voters saw Cornyn as detached from Trump. In a party that has largely embraced the former president’s agenda and style, that perception was enough to sink an established incumbent.
On the Democratic side, the dynamic is nearly the reverse. Democratic primary voters are punishing candidates they view as too cautious, too centrist, or simply too entrenched β even those who have been vocal critics of Trump.
Take Representative Dan Goldman of New York. By any reasonable measure, Goldman was a fierce Trump foe. He appeared on MSNBC almost daily to bash the former president. Yet he still lost his primary. The message from voters, as Canto suggests, may have been that he didn’t hate Trump enough β or at least that his opposition wasn’t sufficiently performative for the current mood of the party’s base.
Similarly, Texas Representative Al Green, who became known for his theatrical protests during Trump’s addresses to Congress, went down to defeat. Green’s performances were a staple of Democratic resistance β but they weren’t enough. In the eyes of primary voters, he apparently wasn’t performative enough either.
The forces behind the wave
What’s driving this surge of anti-incumbent sentiment? It’s tempting to frame it as a simple case of voters wanting change for the sake of change, but the pattern suggests something more specific.
Among Republicans, the test is clear: love Trump 24/7, or expect a primary challenge. Candidates who have been lukewarm in their support, or who have criticized Trump even on policy grounds, have become targets. The party’s base is demanding ideological purity, and Trump loyalty is the primary metric.
Among Democrats, the test is almost the opposite: you must demonstrate your opposition to Trump constantly and convincingly. But even that may not be enough. Goldman and Green both opposed Trump vocally and consistently β yet they still lost. The bar keeps rising, and incumbents who have been in office for years may find it difficult to convince voters that they are truly part of the resistance rather than part of the establishment.
What does this mean for November?
The long-term consequences of this primary wave remain unclear. Canto suggests that the GOP may weather the storm better than the Democrats, who are, in his words, “under attack by the left.”
The logic is that Republican primary voters are largely unified behind Trump, and the candidates who emerge from these primaries will be stronger, more loyal advocates of his agenda. On the Democratic side, the pressure to be more progressive, more combative, and more anti-Trump could push candidates to the left β a position that may not serve them well in a general election.
But that’s a theory, not a certainty. Primary electorates are smaller and more ideologically extreme than general election electorates. Candidates who win by appealing to the base may find themselves out of step with the broader electorate in November.
There’s also the question of whether this wave will continue. More than a dozen states have yet to hold their primaries, and the incumbent casualty count could rise. If the trend holds, 2026 could go down as the year when incumbency became a liability rather than an advantage in both parties.
The season of the primary
For now, all eyes are on Wisconsin, where voters are casting ballots today. But the bigger story is the one that has been unfolding all year: a wave of primary defeats that has already made history and is likely to continue.
As Canto puts it, “It is the season of the primary, and let’s see who is still standing on election night.”
The answer to that question will depend, in large part, on how well the winners of these primaries β whether they are torchbearers of Trump loyalty on the right or fierce resisters on the left β can translate their primary victories into general election success. The incumbents who lost have learned their lesson: in 2026, no seat is safe, and the political ground can shift beneath you at any moment.
Whether this wave is good or bad for the country remains to be seen. But one thing is certain: the 2026 primary season has already left its mark on American politics, and it’s not over yet.
