I figure the GOPe would be betting on Kasich to take PA, and I have no idea who they think would take CA, if not Trump. Sounds like a plan of "wing it" and "hope." Pretty much how they govern too.
I haven't "done the math," so don't have a handle on any "must have" states for Trump, and any "must have" states for blocking Trump.
Looks like Trump turned his speed bump into a launching ramp.
