I recall hearing a snarky pundit on TV saying that even with 1237 Trump couldn’t count on winning the first floor vote, because who knows, certain delegates might sleep in or something, and not show up to vote.
I can’t remember who said it, but it stuck with me and has me worrying that even if Trump does earn 1237, it won’t translate into 1237 votes on the floor.
I've been wondering if that was something that Cruz and the GOPE had been trying to accomplish, by having many (most) of the delegates that Trump "won" and who are bound to him, simply not show up for the first round (along with the alternates).
I know the rule which says that a bound delegate cannot vote for someone other than the candidate he's bound to, and if he does the vote will be counted towards the candidate he's bound to. But I'm not sure if the rule explicitly covers the case of the delegate AND his alternate not showing up.
