No, it is not that they were no longer Democrats — it is that if they were selected to be a delegate at the state convention, they had to register as a delegate by the May 1 deadline. If they did not, they could not be included as a delegate. I was going to be a delegate for the county convention but had to back out due to a family emergency.
It was not a change of party designation or a change — but registering to be an official delegate. Not funny business — just the rules.
