I believe that is accurate. Following the first vote, delegates are free to change their votes.
The delegates pleged to BHO would be free to burn down the convention ceter.
Anyone know anything about the 76-81 (depending on if Mich. and Fla. are allowed to participate?) “add-on” delegates, which I think are not picked until the convention? Could the add-ons end up being the ones to make the final choice?
