I could see Trump/Kasich (Trump said he wanted a vp with political experience in DC) and a nomination to the SC for Cruz.
Kasich is 180 degrees from Trump on the critical issues of immigration and trade policy. He would be a disaster and if anything happened to Trump, we'd have a president who opposed the issues that won it for Trump.
Trump now has plenty of time to decide on a VP and it should not be Kasich.
