Delegates chose between Republican gubernatorial candidates Geoff Diehl and Chris Doughty, and picked Diehl by a 71-29 margin, which still assures Doughty a position on the primary ballot.
Meanwhile, candidates for lieutenant governor Leah Allen Cole and Kate Campanale finished 1-2, with Cole outdistancing Campanale by nearly the exact same number.
Candidates were required to obtain at least 15 percent of delegates' votes in order to qualify for the primary in September.
Diehl, the preferred nominee, vowed to rehire every state employee fired under the state's COVID-19 vaccine mandate -- "and issue pink slips" to those who took away their jobs.
Saturday's undercard saw uncontested candidates Anthony Amore, running for state auditor, Rayla Campbell, running for secretary of the commonwealth, and Jay McMahon, running for state attorney general, delivering stirring speeches that brought delegates to their feet.
Meanwhile, featured speakers included Florida U.S. Rep. Byron Donalds, a member of the House Freedom Caucus; Thomas Homan, acting U.S. Immigration and Customs Enforcement Director under President Donald Trump, and David Bereit, founder of the 40 Days for Life movement.
"The energy for a new direction for Massachusetts is out there, and our candidates are busy tapping into that energy," Lyons later said. "Between now and Election Day in November, we will be going full-tilt.
"Freedom lies in being bold, and that's what the Massachusetts Republican Party is and will continue to be."
