In my opinion, I don’t think Trump wanted to keep Ryan. I think those around Trump including Reince, Pence, etc. encouraged him to keep Ryan and Trump went along with it for the sake of unity. We know Bannon’s Breitbart does not like Ryan. It would be very interesting to see what would have happened if Trump had a non-establishment VP and staff there. Perhaps Trump would not have supported Ryan and there would have been dispute over his becoming Speaker among the Republicans in the House.
That’s what worried me -Trump compromising is ok as long as we have Trump watching over things. He can change his mind if need be. But being stuck with Pence post Trump has me unhappy with any permanent change Trump will be trying to make. Pence can undo it, just like Bush did.
