NOTE: PA is weird... 17 delegates are assigned by the overall winner ("WTA"), but 54 delegates (3 in each of the 18 districts) are elected directly, without the voter knowing exactly which candidate they support! The ballot simply says "uncommitted". Those 54 could all go to Kasich, even if the vote is 48-48-4 with Kasich on the bottom.
There is a list out on Twitter of who the PA delegates are supporting. Looks like most say they will go with their district winner. About 20 each are for Cruz and Trump. They could only find 1 or 2 who said they might at least be thinking of backing Kasich.
2 of the Cruz delegates were winning delegates in 2012, none of the Trumpers.
