Like...himself?
There are two reasons he’s even still in this:
1) To deny Trump Ohio’s 66 delegates.
2) To try to angle his way into being somebody (i.e. Trump’s) Veep.
Probably won’t work, but 66 delegates do provide some leverage.
I think he was also supposed to take delegates from Trump in the northeast, but that didn’t work out. He even lost the county in PA that he was born in.
I’d volunteer the family pussy cat for the office. But she’s too smart to accept.
Cruz who is trying to get Kasich out of the race probably didn’t realize the Ohio delegates with Kasich will automatically go to the 2nd place finisher if Kasich leave race
There is a third reason: hope that the GOPe/Cruz alliance can get it to a second ballot, and then that the GOPe will be able to grab it from Cruz, but not quite bold enough or able to bring Ryan in as a completely new candidate.
