Dem establishment rocked, Laubacher rolls

Primary night delivered major generational and ideological jolts and gave Republican U.S. Rep. Lauren Boebert a well-heeled November challenger.

The intrigue: Whooo, baby. What an election.

✅ CD-4 Democratic primary

Democrat Eileen Laubacher defeated write-in candidate Jenna Preston in a district that includes parts of Arapahoe County.

The big picture: She won handily.

Why it matters: Laubacher's win sets up November's showdown with Boebert in Colorado's sprawling 4th Congressional District.

The intrigue: The former Republican and retired Navy rear admiral from Highlands Ranch gives Democrats a candidate they think can win over moderate Republicans and right-leaning independents in the deep-red district.

• The 57-year-old served as a senior defense official and was on former President Biden's National Security Council.

Follow the money: Laubacher had more than $3 million on hand as of June 10, the Federal Election Commission reports.

• Boebert so far has posted weak fundraising figures.

Reality check: Boebert won CD-4 by nearly 12 percentage points in 2024.

✅ Democratic primary for governor

Weiser will face either Republican State Sen. Barb Kirkmeyer or political newcomer Victor Marx in November.

✅ Republican primary for governor

Kirkmeyer was in a dead heat late last night with Marx.

Why it matters: Republicans are looking for signs of life after years of statewide losses.

✅ Democratic primary for attorney general

Jena Griswold won her race and makes the two-term secretary of state the front-runner for one of Colorado's most powerful elected offices.

What's next: She faces Republican Michael Allen, who won his primary.

✅ CD-1 Democratic primary

Kiros — a former Aurora resident — ousted a 15-term incumbent in a race that underscored progressives' rising power.

Why it matters: Her win proves the revolution is real within the Democratic party this election year.

The bottom line: The stakes are even higher in November.
