As a trio of Republicans and a pair of Democrats sought their party’s nomination for Colorado state treasurer in the June primary, two Democrats vied for the attorney general’s post.

The winners advance to the November ballot in a contest to fill a pair of soon-to-be open positions in state government.

The GOP contest for treasurer and the Democrats’ faceoff for AG both featured battles between the parties’ mainstream and more hard-core versions, and strategists say the outcomes could well determine which races are competitive in the general election.

The November winner in the treasurer’s race will replace term-limited Walker Stapleton, and the next attorney general will succeed Cynthia Coffman. Stapleton and Coffman, both Republicans, sought this year to succeed John Hickenlooper as governor, but Coffman failed to make the primary ballot.

The treasurer’s office has served as a launching pad for gubernatorial candidates in recent decades. Republican Bill Owens and Democrat Roy Romer both successfully made the leap from treasurer.

On the GOP side, state Rep. Justin Everett, R-Littleton, ran a lean campaign for treasurer from the right against centrists state Rep. Polly Lawrence, R-Roxborough Park, and Brian Watson, a real estate mogul, who both poured their own money into their campaign coffers.

The Democrats running for treasurer faced off across the Hillary Clinton-Bernie Sanders divide etched into the party during the 2016 presidential primaries, with state Rep. Dave Young, D-Greeley, a former teacher, occupying the establishment position and financial professional Bernard Douthit mounting a run from the unabashed left.

In the attorney general’s race, Phil Weiser, a former University of Colorado Law School dean and Obama administration Justice Department official, faced state Rep. Joe Salazar, D-Thornton, a rabble-rousing civil rights attorney who had an endorsement from Sanders.

The Republican nominee in the race is George Brauchler, the 18th Judicial District attorney. He had been a leading candidate for governor until late last year, having switched to the race after AG Coffman jumped from a re-election bid to an unsuccessful run in the GOP gubernatorial primary.

The only statewide constitutional office with an incumbent running for re-election this year is also the only one without a primary in either party. Secretary of State Wayne Williams, a Republican, is seeking a second term and will face Democrat Jena Griswold in November

The statewide office up for election that isn’t defined in Colorado’s constitution, the at-large member of the University of Colorado Board of Regents, also already has its major-party nominees: Republican Ken Montera and Democrat Lesley Smith, both first-time candidates
