House passes bill restricting party switching ahead of primaries, citing risk of 'party raiding'

The Utah House passed Third Substitute House Bill 197 on Feb. 12, creating a temporary window during which voters already affiliated with a political party cannot switch to another party in the two‑and‑a‑half months before a partisan primary. Representative Tuscher, the bill sponsor, said the change is intended to "prevent what the Supreme Court has called party raiding," citing Rosario v. Rockefeller as precedent for the state's interest in protecting primary elections from strategic manipulation.

"In 02/2020, over 20,000 Utah registered Democrats switched their voter affiliation to vote in the Republican primary," Representative Tuscher said on the floor, arguing the moratorium would reduce gamesmanship and increase integrity in the nomination process. He emphasized the measure would not apply to new voters and would not restrict unaffiliated voters' ability to register before the April deadline.

Opponents framed the bill as restrictive of voter access and warned of potential political consequences. Representative Briscoe questioned whether the 2020 gubernatorial primary example constituted deliberate "party raiding" or reflected voters making genuine choices; Representative King described the proposal as "bad policy" that could push the majority party toward ideological extremes.

The House adopted the third substitute and voted to pass the bill. Floor proceedings later included a clerk-supported technical sequence to allow Representative Pitcher, who had connection difficulties during the roll call, to state and have her vote entered on the record. The tally reported on the floor was 40 yeas and 30 nays. The bill will be transmitted to the Senate for consideration.
