SCENARIO 1: One candidate emerges with a big delegate lead and is on track for or close to on track for a majority.
That candidate would be the near-certain nominee.
That would make that person the favorite to get the nomination — eventually. But their rivals could keep campaigning to try to block them from a majority.
This would effectively set up a head-to-head contest going forward. Also means a contested convention is unlikely since delegates are being split two ways. Like 2008 and 2016
This is the scenario that's most likely to lead to a contested convention. Especially if the three-way split continues two more weeks in March.
