Vance’s Iowa Visit Turns a House Race Into a 2028 Test
The vice president is stumping for Zach Nunn, but the real audience is Iowa’s first-in-line Republicans and rivals sizing up 2028.
J.D. Vance is turning a 2026 House stop into an early 2028 audition. He is traveling to Iowa to campaign with Rep. Zach Nunn in the Des Moines area, in what AP describes as his first visit to the state since taking office and one that comes less than two years before Iowa Republicans are expected to cast the party’s first presidential-nominating votes.

Why Iowa matters now
In 
US Politics, Iowa travel this early is rarely accidental. Iowa GOP chairman Jeff Kaufmann said at the 2024 Republican convention that the 2028 “pregame” began as soon as Donald Trump locked down the last nomination, and former House Speaker Newt Gingrich said then that Vance would be the front-runner if Trump won.

That gives Vance an unusual advantage. Because Trump cannot run again in 2028, the vice president can use official travel and midterm campaigning to build relationships in the first Republican state without formally opening a presidential campaign.

Front-runner status has limits
The evidence says Vance leads the succession contest, but not decisively enough to clear the field. Reuters reported that he won CPAC’s 2026 straw poll with about 53% support, while Secretary of State Marco Rubio took 35%, a sign that the MAGA base still sees Vance as first among plausible heirs but not the only one.

Iowa is also where inevitability goes to be tested. AP notes that Ted Cruz, another possible 2028 contender, had just addressed influential Iowa evangelicals before Vance’s trip, and Iowa Republicans have a record of embarrassing presumed favorites, backing Cruz over Trump in 2016 and Rick Santorum over Mitt Romney in 2012.

What to watch next
The real constraint on Vance is still Trump. GOP strategist Alex Conant told AP that Republicans are “treading very lightly” and will be reluctant to get in Trump’s way until he gives the green light for the 2028 race to begin in earnest.

The next thing to watch is simple: whether Vance comes back to Iowa again after the midterms, when, as Conant put it, the early-state scramble becomes “irresistible.” Vance gets a chance to woo Iowa Republican voters ahead of 2028
