A new report has revealed that the “nonpartisan” Congressional Budget Office (CBO), which is tasked with providing Congress cost estimates for proposed policies, may not be as neutral as we were led to believe.

Established in 1974, the objective of the CBO was to “provide objective, nonpartisan information to support the Congressional budget process and to help the Congress make effective budget and economic policy.”

But according to a new report from the Foundation for Government Accountability (FGA), which is a public policy think tank that leans right-of-center, the staff that works for the agency is made up mostly of Democrats. Making matters worse is the CBO’s lengthy history of making scoring errors that benefit proposals from Democrats.

When looking into the voter registration records of CBO employees, FGA found that 78.9 percent were part of the Democratic Party. Only 12.5 percent were Republican, and 8.6 percent registered as independent or unaffiliated.

Certain departments in the agency have a higher percentage of Democrats than others, such as the Health Division. This is the department tasked with producing estimates for Medicare, Medicaid, and other programs. The FGA report revealed that 93 percent of the staff are Democrats.

According to The Daily Caller, even among staff members who identified as independent, donation records show significant political donations made to Democrats, which means the actual, legitimate percentage of liberal employees in the agency is likely even higher than the initial findings of the report.

 “The CBO loves to say they’re just doing math — but when that math is built on partisan bias and bad assumptions, it becomes political storytelling rather than hard science,” Hayden Dublois, data and analytics director at the FGA, and a co-author of the report, went on to say during an interview with the Daily Caller News Foundation.

The FGA report explained that the reason for the ideological skew was a “revolving-door-like relationship with both liberal members of Congress and left-leaning think tanks, where CBO’s analysts often gain their political experience before scoring the most important piece of legislation.”

“The report’s findings follow heightened scrutiny of the CBO’s projections for the GOP’s One Big Beautiful Bill Act, aimed at advancing President Donald Trump’s agenda via the budget reconciliation process. On Wednesday, the CBO estimated that the bill could increase the federal deficit by $2.4 trillion and leave almost 11 million uninsured due to Medicaid changes,” the Daily Caller said.

Despite the CBO’s projection, which experts inside and outside the Trump administration will take with a grain of salt, the “big, beautiful bill” is predicted to slash the deficit by $1.4 trillion.

Folks at the FGA are making the case that members of Congress shouldn’t trust the projections and data coming out of the CBO, saying it has a “disastrous track record” when it comes to forecasting the impact of reforms made to entitlement programs like Medicaid.

“CBO makes scary claims about how many people will lose Medicaid, but they leave out the truth: The vast majority of those counted are either enrolled in multiple states, already ineligible, have other health coverage, are illegal aliens, are able-bodied adults who can work but choose not to, or aren’t even enrolled in the program,” Dublois continued, speaking of the current reconciliation bill.

“Here’s the bottom line: CBO is biased, and its numbers consistently miss the mark by embarrassing margins,” Dublois remarked. “Congress should be able to rely on its service agency to produce quality data. Instead, CBO has become another captive institution wrapped in non-partisan clothing.”
