The claim is mostly true because available reports document Democratic registration declines of tens of thousands in specific places, although it is too vague to establish that Democrats lost that number of actual voters nationwide.

Key Evidence
The Nevada report gives a specific figure of 33,509 fewer active registered Democrats in 2025, directly supporting the “tens of thousands” wording in that state.

What the Evidence Shows
The statement is supported when interpreted as a claim about registered Democratic party members in particular states or districts:
- The Reno Gazette Journal reported that Nevada Democrats lost 33,509 registered party members during 2025, based on final active-voter figures. The same report noted that Republicans also lost 26,207 members.

- NOTUS reported that Democrats lost more than 275,000 registered voters across general-election battleground districts, averaging roughly 10,000 per district.

- Other reports describe a broader decline between 2020 and 2024: Democrats reportedly lost 2.1 million registered voters across 30 states that track registration by party, while Republicans gained 2.4 million.

However, the wording has important limitations. It does not identify a location, time period, or definition of “voters.” The evidence primarily concerns party registration, not necessarily people who stopped voting for Democrats in elections. Registration changes can reflect people changing party affiliation, becoming unaffiliated, moving, being removed from voter rolls, or differing state registration practices. The available sources therefore support the narrower claim that Democrats lost tens of thousands of registered members in certain jurisdictions, but they do not by themselves prove a nationwide loss of tens of thousands of actual Democratic voters.
Some sources are opinion, partisan analysis, or social-media discussion rather than independent primary documentation. The evidence is strongest for the Nevada-specific figure and for the existence of registration declines, but the causes and national implications remain less certain.
