"For those who will back Clinton, for example, their vote next to her name is the only one that matters for determining how many delegates she’ll get. So if they happen to really like one or two of Sanders’ delegates, they can give them their backing to increase the odds that they’ll be one of the proportional delegates he’s awarded, without worrying about decreasing the number of delegates Clinton will receive."

"Since this vote on delegates won’t have any impact on who will actually win New York’s presidential primary, many voters could probably care less. But for those who might happen to adore their state legislator but abhor their mayor, voting for only the former would increase the odds that the mayor would get the honor of being elected as a convention delegate. Voting for only some delegates could also be a valid strategy for residents of sprawling upstate districts who want to make sure somebody from their town rather than one a hundred miles away will get to mingle with powerbrokers."
