In the final days of election season, Democrats spent millions of dollars propping up independent candidate Dan Osborn in his since-unsuccessful bid to oust Sen. Deb Fischer (R-NE), according to the latest Federal Election Commission filings.

The money, much of which was routed to a super PAC called Retire Career Politicians that purchased ads boosting Osborn, is the latest illustration of how the independent relied on influential Democratic donors to support his 2024 candidacy. Retire Career Politicians raked in $3.8 million from the Schumer-aligned Senate Majority PAC and funding from the likes of Sixteen Thirty Fund, a key cog in a massive Democratic dark money network called Arabella Advisors, filings show.
