2025 Utah Senate Special Election Buss was selected as the Forward Party of Utah's candidate to replace outgoing state senator Daniel Thatcher in Utah's 11th district on December 12, 2025. According to the Forward Party, this was the first time in United States history that approval voting was used to elect a state legislator, and the first time that a political party in the nation opened a replacement vote to all registered voters in a district, regardless of party. Typically, political parties in Utah let only local party delegates in the district vote on replacement legislators. In-person, online, and mail-in voting took place over multiple days, and prospective candidates pledged not to exceed a $300 campaign spending limit. Buss spent $0 on her special election campaign. Following the poll, the Forward Party formally submitted her name to the Governor who, under Utah law, was required to appoint a replacement chosen by the outgoing legislator's political party.
