‘The Biggest Loser’ trainer Cara Castronuova files petitions to run in the Republican NY primary for US Senate

Cara Castronuova, a former Golden Gloves boxing champ and celebrity fitness trainer on the reality show “The Biggest Loser,” claims she’s collected enough signatures to run in the Republican primary for US Senate against retired NYPD detective Mike Sapraicone.

Both Castronuova, who’s recently worked as a Newsmax reporter, and another wannabe GOP candidate, businessman Josh Eisen, filed petitions to qualify for the ballot, the state Board of Elections confirmed Monday.

If their petitions are not successfully challenged, the two would face off against Sapraicone — with the winner then taking on heavily favored three-term Democratic incumbent Sen. Kirsten Gillibrand on November 5.

Sapraicone beat out Castronuova and Eisen for the party nod at the state convention in February.

Former President Donald Trump, the 2024 Republican nominee for the White House, also endorsed Sapraicone.

Both Castronuova and Eisen failed to garner 25% of the weighted delegates’ vote to qualify for ballot status to run in a Republican primary.

The only other way to get on the ballot is to collect 15,000 signatures from registered Republicans, with at least 100 from 13 of the 26 congressional districts.

Castronuova filed a designated petition on April 4 that contained 35 volumes with more than 3,500 pages of signatures, a BOE spokesperson said.

Eisen’s filing contained 16 volumes and 1,500 pages, the spokesperson added.

As of Monday, Castronuova’s petitions haven’t been challenged to knock her off the ballot.

But that could change.

General objections must be filed by the end of day Monday, with specific objections to voter signatures filed six days later.

“We’ll see what happens. I do expect the petitions will be challenged. The parties don’t like primaries,” Castronuova said Monday.

She recently filed a federal lawsuit claiming New York’s ballot requirements are too onerous.
