It might be an improvement in ground game. The ground game was good, I just can’t compare it to other states since I don’t live there. This is a very different kind of delegate management though. This one depends on getting the same voters who are voting for you to vote for the delegates. That’s really just slightly altering your campaign message in the state, but still going through all the same channels to reach the voters you normally would.
Illinois has a similar system, except the ballot tells you which candidate the delegates are for, so I assume they don’t need to spend much time campaigning for the delegates.
Well I am comparing them with a balanced ignorance, since my state has not voted yet, and the primary is fairly straightforward here (CA).
