Nikki CHOSE to run in the primary, rather than the caucus. Why did she do that if it was such a scam? All the other candidates (DeSantis, Ramaswamy, etc.) chose the caucus, instead. She deliberately chose to skip the caucus, which she knew she would lose, so she could win a symbolic victory by being the winner of a primary in which she was the only candidate - and she STILL lost.
NIKKI ALSO DID NOT PAY THE FEE FOR THE CAUCUS
