SEE IT: Billboards emerge as GOP campaign trolls 'fake Independent' Senate candidate with socialist theme

The campaign to re-elect Sen. Pete Ricketts, R-Neb., is deploying mobile billboard trucks with bold, neon graphics portraying his rival, Independent candidate Dan Osborn, as a "fake Independent" and part of the Democratic Party's far-left future, along with New York City's socialist Mayor-elect Zohran Mamdani and controversial Maine candidate Graham Platner.

Omaha is considered a "blue dot" in Republican-leaning Nebraska. Nebraska is one of only two states that splits its electoral votes by congressional district, and Nebraska's 2nd Congressional District, which includes Omaha, typically votes for the Democratic presidential nominee. 

While the district voted for former Vice President Kamala Harris in 2024, Republican Rep. Don Bacon nevertheless won re-election for his U.S. House seat in that same district. Bacon is not seeking re-election in 2026. 

While Osborn is running as an Independent, Chair Jane Kleeb has affirmed the Nebraska Democratic Party is "supporting" his bid to unseat Ricketts, the two-term senator and former Nebraska governor.

The Ricketts campaign has called Osborn a "fake" Independent - another message that will be on display around downtown Omaha Friday.

"Osborn's campaign is even staffed by the same people who ran Socialist Zohran Mamdani's campaign in New York. A communist, a socialist, and a Fake Independent: that's the best the Democratic Party has to offer," Coup told Fox News Digital.

Between 2020 and 2021, Platner posted and has since deleted Reddit posts calling himself a "communist," which he recently said he was "joking" about.

An image of Platner with "communist" plastered across his face will be featured on one of the mobile billboards, alongside the message "fake 'Independent'" on Osborn and "socialist" on Mamdani, above a slogan describing the "future of the Democratic Party."

Osborn, a union leader who ran as an Independent against Sen. Deb Fischer, R-Neb., last year, is now mounting his second straight bid to unseat a sitting Republican in the U.S. Senate.

Fox News Digital reached out to the Nebraska Democratic Party, Biden, Platner and Mamdani for comment.
