“You suck, Joni! That’s just the nicest way I can summarize how we’re all feeling about your reign so far,” says Joshua Smith in the first digital ad promoting his Republican campaign for Iowa’s U.S. Senate seat.

The video previews what will be an aggressive campaign by Senator Joni Ernst’s 2026 primary challenger from the right.

UPDATE: Smith fleshed out his message against the incumbent in a digital ad launched on December 31. Original post follows.

Senator Joni Ernst has her first declared 2026 primary challenger. Joshua Smith announced on X/Twitter on December 5 that he plans to run against Ernst as a Republican in 2026. The “blue-collar, working-class veteran” and father of seven promised he would be “the most pro-life, pro-family, small government candidate running for a federal office” next cycle.

So far, Smith’s campaign looks more like a bid for online engagement than a serious threat to Ernst’s career. But in a December 9 telephone interview, he explained why he’s confident he can build a strong GOP primary campaign.
