I do prefer, if he's contra-Trump, that Ryan do so openly and early. Better to get this out of the way before mid-October.
As for the party, it is a vessel holding some people. The vessel is okay, some of the people are okay. It's like any company that way. Might be beyond repair, too early to tell. Without Trump, it is garbage. I won;t vote for the Republicans floated in my state (Maine), and in fact, expend effort to have them defeated.
The big thing for me is Ryan is going out of his way to stab Trump in the back. These interviews are choreographed to gaslight Trump. Ryan’s gratuitous bashing of his party’s nominee is outrageous. It’s like we are the primaries again and Ryan is candidate.
