Hatch's primary turned out to be a rare outcome in major races, with Gov. Gary Herbert, Rep. Rob Bishop and Rep. Jason Chaffetz clinching their party nominations, along with newcomers Love and Stewart . Primary elections will decide the Republican candidates in the race for attorney general, state auditor and a handful of legislative races.
Senate • After two rounds of balloting, Hatch received 2,313 votes or 59.1 percent of the delegate vote. He needed the support of 32 more people to hit the 60 percent threshold and claim the nomination outright.
Eight other challengers, including state Rep. Chris Herrod, were eliminated in the first round, four of them throwing their support to Liljenquist, helping him jump from 28 percent of the vote to just over 40 percent. He left energized.
"It is the time for a new generation of leaders. We know it to our bones," said Liljenquist, 37. "We have two more months. We feel good about our chances."
Hatch will begin the next phase with momentum from convention and far more financial support and says he's confident he will come out ahead this time.
"We're going to win it," he said, calling the vote "a tremendous victory" even if he didn't win the nomination outright.
"We're pretty darn happy about what did happen. It sent a message. It says that this tough old bird isn't someone you can just trample on."
The race has received widespread national attention, with tea party groups such as FreedomWorks targeting Hatch and spending more than $700,000 in a campaign to defeat him and boost Liljenquist.
The senator has spent millions of dollars and amassed a campaign staff of more than two dozen to recruit delegates and fight the tea party wave that consumed former Sen. Bob Bennett at the state convention two years ago.
4th Congressional District • Love, the mayor of Saratoga Springs, pulled a major upset on Saturday, winning the GOP nomination and advancing to face Matheson, Utah's lone Democrat in Congress, in November.
"Today we have an opportunity to do something very special. Today we can start breaking a pattern," Love exhorted delegates before the final vote. "Today we can start bringing Jim Matheson home."
Love won 70.4 percent of the vote from the delegates while Wimmer captured 29.6 percent.
Wimmer had campaigned for the office for more than a year, resigning his legislative seat to make his bid. He had broad legislative backing, the endorsement of Sen. Mike Lee, and the backing of legislators and Attorney General Mark Shurtleff.
If elected to Congress, Love would be the only black Republican woman in Congress.
2nd District • Last-minute allegations of dirty tricks threw Utah's 2nd Congressional District Republican race into turmoil.
Eureka Mayor Milt Hanks alleged right before delegates began casting ballots that four contenders had conspired to drop negative information about Stewart charges that those candidates denied and claimed was foul play by Stewart's camp.
Candidate Howard Wallack said he and other candidates pulled out of the race to try to deny the nomination to Stewart. But he still met the 60 percent threshold, defeating former Utah House speaker David Clark.
"It stinks to high heaven," said state Rep. Greg Hughes, R-Draper, who supports Clark.
Delegates later voted to launch an investigation how the allegations came down.
Other races • Candidates Sean Reyes and John Swallow will face off in a June 26 primary in their quest to replace Attorney General Mark Shurtleff, who is not seeking a third term. The winner of the June 26 primary will run against Democrat Dee Smith in November.
State Auditor Auston Johnson and state Rep. John Dougall also will go to a primary,
In the Utah Senate, incumbent Curt Bramble clinched his nomination, but Sens. Ralph Okerlund, R-Monroe, and Casey Anderson, R-Cedar City, have primaries. Both are challenged by current state House members Rep. Patrick Painter, R-Nephi, and Rep. Evan Vickers, R-Cedar City, respectively.
In the state House, primaries are set between Rep. Bill Wright, R-Holden, and Merrill Nelson; and Reps. Lee Perry, R-Perry, and Brad Galvez, R-West Haven.
