Have to commend Rush for that — on 2nd and additional ballots, delegates CAN vote for Trump or whomever.
That is the first mention I have heard any newsies/talk radio personality say that. They have always emphasized that Cruz (and/or Kasich) have a chance on the 2nd, because they have the delegates tied up. They seldom mention that Trump might get MORE delegates previously pledged to another.
Several of us on FR has mention that numerous times — the 2nd ballot is not a lock for Cruz.
Additionally, the unbound delegates are actually free to vote as they wish on the 1st ballot.
It's called POLITICS for a reason.
