Preliminary voting results from Utah's primary elections on Tuesday night showed a potential shake-up in the Utah Senate minority party as incumbents duked it out with challengers.

Utah County Attorney David Leavitt — the subject of recent controversy amid an ongoing conflict with other county leaders — also appears to be potentially on his way out as his opponent Jeff Gray took an early 72-27% lead.

Sen. Derek Kitchen, D-Salt Lake City, and challenger Jen Plumb are separated by less than two percentage points, with Kitchen leading 50.87-49.13%, making that Salt Lake County race one of the tightest of the primary elections so far.

Kitchen, one of the youngest and the only openly gay lawmaker in the state Legislature, has served in the Senate since 2018.

Sen. Gene Davis, D-Salt Lake City, a longtime lawmaker and minority caucus leader, appeared to be threatened with being ousted by challenger Nate Blouin, according to preliminary numbers that showed Blouin with nearly 73% of the vote. Davis has served in the Senate since 1999.

The 23 state Senate and House races on primary day will determine many of the candidates for the Utah Legislature during the general election this November.

The new voting boundaries, though not yet in effect until 2022, apply to this year's elections. That means some voters found themselves in new districts. To view your district, visit the state Legislature's website.

Two close races for positions on the Utah Board of Education in Salt Lake, Davis, Weber and Utah counties brought large turn-outs.

Numerous other county leadership primary elections also took place on Tuesday. Among them, longtime Salt Lake County Councilman Steve DeBry is behind in the race against his challenger, Sheldon Stewart. Debry has served on the council since 2010.

Polls closed at 8 p.m., and the results won't be finalized until all ballots are counted. These are unofficial and incomplete results in legislative races and other races of note, but here's who's leading on the ballots in your area as of just before 11 p.m. Tuesday:
