Everything you just said.... except with Rubio’s 171 delegates.
Rubio said yesterday that his delegates should go to a Conservative, and that Cruz is the only Conservative left in the race. (Remember, they teamed up to attack Trump that one debate.)
I’m not sure Rubio has control over his delegates the same way Kasich does (at least on the 1st ballot).
Did Rubio officially withdraw from the race or suspend his campaign? If he ended his campaign, his delegates may no longer be officially bound, but may new be uncommitted delegates on the 1st ballot.
