I'm not sure what is going to happen but apparently the GOP still hasn't released the official slate of delegate names yet, which apparently is unusual.
What is really odd is that you have a nominee not supporting his party - Trump isn't campaigning for down ticket candidates or raising money for the party - and a party that isn't supporting its candidate. It's a pretty tenuous connection right now as it is.
Trump yesterday was claiming that Jeb is plotting against him, and he lashed out at Cruz, and he is now saying he may self fund again.
If this was a married couple they'd be taking separate cars to social events and have their money in separate accounts.
