Cara Castronuova, a former Golden Gloves boxing champ and celebrity fitness traineron 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.
