From party switch to $6.4 million: Examining the rise of a CD4 candidate

By Shaina Cole | Contributing Writer, Rocky Mountain Voice

In a matter of months, Eileen Laubacher went from a newly registered Democrat with no primary voting history to the best-funded candidate in Colorado’s 4th Congressional District.

That kind of political acceleration is unusual on its own. What makes it more striking is how many pieces had to move at once to get there.

Her party registration, then and now

In Jefferson County, Laubacher shows up as a registered Republican as far back as 1998. That didn’t change until January 2024, when she went unaffiliated, followed by a switch to Democrat two months later using her Ken Caryl address.

She filed to run for Congress not long after. It would be more than four months before her voter registration was updated to CD-4 on September 17, 2025.

Laubacher has offered different explanations for that political trajectory, depending on where she’s speaking.

On the Get More Smarter podcast, she pointed to John McCain when explaining her 1998 Republican registration. “I love John McCain. You know, he was a fellow Naval Academy graduate and a war hero. When he was running against George W. Bush back in 2000, I really wanted him to be the candidate. And so that was why I registered as a Republican,” said Laubacher.

At a town hall in Haxtun a little over a month earlier, she offered a different account, describing herself as “a Republican and a great admirer of Senator John McCain around the time he ran for President against Barack Obama” — a reference to the 2008 race, not 2000.

The two explanations cite different elections as the reason for the same registration decision.

Neither fully accounts for the timing. Laubacher registered as a Republican in January 1998, roughly twenty months before McCain entered the presidential race. It was also a decade before he ran against Obama, and she did not vote in the 2000 primary when McCain was on the ballot.

On the podcast she also suggested that party registration was required to vote in primaries at the time, saying “In order to vote in primaries, you had to be in a party. It’s not like now where you can be unaffiliated and vote in a primary.”

Colorado has allowed unaffiliated voters to participate in statewide primary elections since 2016, well after her 1998 registration.

Laubacher has pointed to January 6, 2021 as the moment she decided to leave the Republican Party. “That was really hard to watch…I knew I couldn’t be a part of that,” she explained at the town hall in Haxtun.

Residency and District Alignment

Those questions take on a different shape when you look at where she was living at the time she entered the race.

When Laubacher filed her candidacy for Colorado’s 4th Congressional District, she was still registered to vote in Jefferson County, which is in CD-7. Her FEC Statement of Candidacy listed a UPS Store address in Highlands Ranch.

Using a mailing address or post office box is common practice for campaigns for privacy and security reasons, but it does not establish that a candidate has physically moved into a district.

That filing predates her voter registration change into the district by several months.

Laubacher and her husband still own a home in Ken Caryl in Jefferson County, with property taxes paid as recently as February 2026, according to assessor records. Her own Federal Election Commission contribution records—including a January 23, 2026 donation—list a Littleton address and identify her occupation as “Not Employed” — a designation that appears in filings from the same period in which she disclosed consulting income from two separate firms.

An actively maintained LinkedIn profile—updated as recently as March 2026—also continues to list Littleton as her location.

The address she now uses in Highlands Ranch falls inside CD-4, but it is a rental property.

On that same podcast, she described the move by saying, “So, right now, we live in Highlands Ranch. This is our new Highlands Ranch home… Chris and I have moved into this place,” while also describing herself as “a regular Coloradan with a mortgage and car loans.”

The mortgage she references is tied to the Ken Caryl property outside the district she is seeking to represent.

Ballot Eligibility and Ongoing Lawsuit

Those timelines—party affiliation, voting participation, and residency—have now become part of a legal challenge.

At issue is whether she qualified for the ballot through the Democrat assembly process at all.

According to an ongoing lawsuit, candidates must be registered as Democrat for twelve consecutive months. Laubacher registered on March 27, 2025. The original assembly date was March 26, 2026—one day short.

The date was then moved to March 27.

Party Chair Shad Murib defended the decision, calling it an “elegant solution” and arguing that party rules are meant to enable participation rather than restrict it.

Laubacher’s primary opponent and the district’s Democrat central committee chair Trisha Calvarese, along with Lisa Chollet filed the lawsuit challenging that move. According to the lawsuit, the change wasn’t properly authorized and was made to let her qualify. The process is moving forward for now, after a judge declined to stop it. The case itself is still unresolved.

Fundraising and Financial Structure

Set against that backdrop, Laubacher’s fundraising stands out even more.

In less than eight months, she raised more than $6.4 million. This outpaced every other candidate in the race—Democrat and Republican alike.

Her campaign has also claimed she raised “fourteen times more” than Lauren Boebert. That figure reflects a single quarterly comparison. Federal Election Commission data shows the full-cycle total is closer to 8.9 times.

At first glance, the total alone is enough to separate her from the field. But the structure of that fundraising begins to tell a different story.

Looking at the itemized data, Colorado accounts for a limited share. Of roughly $1.3 million in itemized contributions, about $299,000 comes from within the state, spread across 2,019 donations. The rest comes from outside Colorado, with California standing out as the next largest source.

That pattern becomes clearer in the broader totals. Itemized donations represent only part of what the campaign has raised. More than $5 million comes from smaller, unitemized contributions—money that can’t be tied to a specific location in federal filings.

The campaign has stated it has more than 16,500 Colorado donors. That figure isn’t something that can be verified independently using FEC data, since those smaller donations don’t include geographic detail.

What can be verified is the distribution of those contributions.

Among larger donations, roughly three out of every four dollars come from outside Colorado. Even among the smaller share that can be traced, the district she is running to represent accounts for only a limited portion of the total.

But the pattern goes beyond any single network. The campaign has leaned into a national message—framing the race as an opportunity to defeat Lauren Boebert. That message appears to have attracted donors beyond the district.

Financially, the campaign reflects that. The campaign reflects a nationalized fundraising profile rather than a primarily district-based one.

Endorsements and Institutional Support

That national profile is reinforced by the endorsements she has received.

One of the groups backing Laubacher is the Steady State. It’s made up of more than 300 former national security officials, including people who have worked in the CIA, NSA, Department of Defense, and State Department.

The group calls itself nonpartisan. Their endorsements since its creation have mostly gone to Democrat candidates.

The organization endorsed Virginia Governor Abigail Spanberger just days before endorsing Laubacher. Spanberger has since backed a series of gun control measures, including an assault weapons ban awaiting her signature.

Her direct PAC support, by comparison, is relatively limited. Federal filings show she has received just over $13,000 from political committees. Of that total, $5,000—more than a third—came from VoteVets, a progressive political action committee focused on national security and veterans’ issues. Additional contributions include support from DUTCH PAC, associated with Rep. Dutch Ruppersberger, a senior member of the House Intelligence Committee.

Taken together, the funding and institutional support begin to answer part of the question raised at the outset—how a first-time Democrat candidate with no primary voting history was able to assemble a campaign of this scale so quickly.

Claims and Verifiable Data

But questions about alignment between messaging and measurable reality do not end there.

On the campaign trail, Laubacher has repeatedly said that 43 percent of households in Colorado’s 4th Congressional District are veteran households. She has made the claim in multiple public settings, including a candidate forum and podcast appearances.

There are roughly 39,000 veterans in the district, according to Census data, making up about 6.5 percent of the population. They’re spread across nearly 300,000 households. That works out to roughly 13 percent—assuming each veteran lives in a separate household.

The difference is notable, and she has repeated the claim in multiple public settings.

Public Record and Narrative Changes

Public edits to her Wikipedia page also drew attention.

Between June and August 2025, a Wikipedia account called “Nothingbutwordswordswords” made at least seventeen documented attempts to remove verified references to Laubacher’s Republican registration history and her residence outside the district. The same account replaced those details with campaign fundraising language and also edited the page of her primary opponent.

Many of those edits didn’t stick. They were reversed by moderators.

Who was behind the account isn’t known.

The Broader Pattern

Any one of these differences could be explained away on its own. When combined, these elements raise recurring questions across multiple phases of her campaign.

A late party switch after decades in another affiliation. A limited record of participation in elections. Entry into the race before establishing residence in the district. Eligibility that hinges on a one-day change in party scheduling. A fundraising base that extends far beyond the state. And public claims that do not always align with available data.

Whether she makes the ballot through the assembly process is still an open question. If the lawsuit fails, it won’t be settled in court—it will be decided by voters in Colorado’s 4th Congressional District.
