Democrats are spending hard and fast to try to unseat U.S. Rep. Lauren Boebert in Colorado’s 4th Congressional District. This race went from sleepy to splashy as national groups and a well‑funded Democratic challenger poured millions into the contest. The new development to watch is the cash: huge outside spending and big fundraising totals for the Democrat, aimed at knocking off a high‑profile Republican.
Democrats pour millions into CO‑04
Independent trackers put total spending in the Colorado 4th contest north of $13 million, with Democrats outspending Republicans by about $11–$12 million. The leading Democratic challenger, Navy veteran Eileen Laubacher, has reported roughly $8.5 million raised and a large share coming from small donors, while U.S. Rep. Lauren Boebert is working with far less cash on hand. That money is already paying for ads and staffing, and more independent expenditures from national groups are expected to come.
Why the money? Boebert’s profile and intra‑party drama
Why the heavy Democratic bet? Boebert is a national figure who draws headlines. Her push on issues like gun rights and the Epstein files made her a lightning rod. Even allies in her party have had an eyebrow‑raising spat with President Trump after she backed Rep. Thomas Massie in a primary — and Mr. Trump even threatened to withdraw his endorsement. That kind of drama makes the race look winnable to donors, so they stepped up the spending.
District leans Republican — spending may not be enough
Here’s the blunt truth: Cook Political Report still ranks CO‑04 as Solid Republican. The district is rural and conservative, covering most of eastern Colorado. Throwing money at a district that reliably votes red is an expensive gamble. Democrats may buy TV time and social media hits, but money can’t change deep partisan geography overnight. If Republicans organize and get voters to the polls, a few million in ads won’t flip the map.
What to watch and the conservative case
The next steps matter. Colorado’s primary on June 30 will settle the Democratic nominee, and FEC filings will show whether outside spending keeps rising. Watch whether Democrats can localize the message on pocketbook issues like fuel and fertilizer costs — or whether Boebert’s campaign turns the narrative to constitutional rights and energy jobs. Conservatives should take the spending seriously but not panic. Big money makes noise. Ground game wins votes. If Republicans mobilize, Boebert can hold the line — and Democrats will have only bought themselves a lot of TV time and a lesson in political arithmetic.
