No, it does not make sense to split the delegates between Obama and Clinton, because the effect of that is just to cancel out their vote. The people who voted in these states do not know anything about party politics. It is not their fault that the party leaders in those states moved up their primaries. Their votes should count.
No, splitting the votes does not make sense because that only has the effect of canceling out those votes. That would be no different than simply not counting those votes at all. The voters in those states do not know about party politics, and they should be able to have a say in this important national election, regardless of strict rules and procedures.
