And thus Kasich needs to stay in the race through Ohio. And I suspect that is why he is staying in. He is doing it for the Pub establishment team. Bless him. 
I question that logic, Torie. As much as i back Kasich, if the goal is to stop Trump then which would the Donald be more concerned about facing here: Kasich who is already behind and will have difficulty maintaining even that level of support after what will likely be a lackluster showing Tuesday (maybe distant 2nd in a couple states at best) plus will have Rubio siphoning the establishment anti-Trump vote; or Rubio if Kasich dropped out and gave his complete public and organizational support to Rubio (in exchange for the Veep slot or at least a cushy cabinet post)?
If the establishment isn't careful , Kasich could wind up giving Trump Ohio rather than saving it from him.
More and more we are seeing this is not a real thing. If Kasich drops out a lot of his voters either won't vote, or even go to Trump. At least enough to block Rubio.
Where do you get that impression, especially among his supporters in Ohio ?
I get that impression from the polls. Most polls show Kasich supporters going to Rubio, sure, but only by margins like 57/26, not the kind of margins Rubio needs.
But let's assume this much - 70% goes to Rubio, 15% to Trump, 10% to Cruz, and 5% Just don't vote. And I'm generous to Rubio and Kasich - I assume 50% of undecideds would go to Kasich, and then if Kasich drops out, whatever margin of rounding for the 5% that don't vote go with Rubio. Rubio still trails Trump 36-34. That is a generous estimate. If it's 60% Rubio, 23% Trump, 12% Cruz, and 5% don't vote, it gets a lot worse - 38%-31%. And again, I'm giving the advantages to Rubio - he gets the rounding error.
The math is just not going to work.
