Well, just knowing the rules should be enough, so I wasn't going to get into the details. She also scheduled her rally that night in Florida right after the polls closed, where all the other candidates stayed away.
And the reason why only her name was on the ballot in Michigan is because all the other candidates voluntarily withdrew their names but her. After she refused to take her name off the ballot in Michigan, the rest of the candidates decided to leave their names on the Florida ballot.
Regardless, the rules are the rules and she signed a pledge. That should be enough. Unless her word is not her word?
