Three Libertarian candidates in Iowa running for the U.S. House will not be listed on ballots this November after a panel ruled they failed to comply with state law, a decision that could affect the outcome of at least one tightly contested race

The state’s objection committee, composed of one Democratic and two Republican elected officials, ruled 2-1 Wednesday in favor of Iowans who challenged the candidates’ legitimacy.

Democrat on the panel who opposed the candidates’ removal, State Auditor Rob Sand, accused his colleagues of political bias, saying in a statement that the decision was “a wrong-headed plot by Iowa’s uniparty to limit voters’ choices.”

One of Iowa's four congressional races was decided by a razor-thin margin in 2022. Republican Zach Nunn, who was challenging incumbent Democrat Cindy Axne, won by less than a percentage point. There was not a third-party candidate.
