Former Rep. Cynthia Lummis won Wyoming's Republican primary for the Senate on Tuesday, defeating a number of challengers and nearly guaranteeing a win in the deep-red state this November, per AP.

The big picture: Lummis, the clear front-runner in Tuesday's race, served in the House from 2009-2017, and was the only woman in the House Freedom Caucus at the time, per CNN. Her election could be significant for GOP gender diversity in the Senate looking ahead.

  • Lummis racked up endorsements from President Trump, retiring Wyoming Sen. Mike Enzi (R) and Wyoming Sen. John Barrasso (R).

"This was the position the Republican Senate took in 2016 when there were almost 10 months to go before the election.
