It hasn’t come up before, last time there was a second ballot was before the modern system of primaries and most delegates being bound.
If no one has a majority going into the convo I assume the rules committee will be voting to clarify things. I don’t see an alternative to allowing delegates to vote as they like on ballots after the first.
the whole David Duke KKK bit reminds me of the “ethnic purity” episode in Jimmy Carter’s ‘76 race.
The matter was brought up right before the southern primaries .... helping Carter, then he repudiated the whole thing as the campaign moved North. It was strategery.
What I concluded from tonite:
-Trump said nice things about Planned Parenthood
-Rubio talked about the KKK and his pick up truck
-Cruz cannot get evangelicals to vote for him
