Most delegates will typically support who their person they supported endorses. So if Rubio endorses Cruz… he would be much closer, much… and this amount of a split in delegates would force — per GOP primary rules — a 2nd ballot at the party convention.

So, right this is the count:

➤ TRUMP: 646
➤ CRUZ: 397
➤ KASICH: 142

RUBIO left the race with 163 delegates. If he endorsed Cruz [like he should… unless he is a weenie and endorses Kasich], That would leave…

➤ CRUZ 560 delegates.

Mind you, these delegates would have a choice to remain uncommitted now and choose who to support at the convention ~ which is July 18–21, 2016.

In-other-words, this will most likely end in a brokered convention, per the already agreed upon rules set for the primaries.
