Pre-Trump I would have put $ that Boehner and McConnell would maintain their joint death grips on power. Post-Trump, the rank and file might just be too scared to keep on betraying the base wholesale.
There is no doubt in my mind that Boehner is gone as speaker after the next election. McConnell seems to have a uncanny way of surviving when he shouldn’t so that’s a harder call. But I do not think he will be a GOP leader post 2016 election. “The Folks” really hate Boehner and McConnell, look what happen to Rand Paul for simply endorsing McConnell in Ky. Paul is toast for just being nice to McConnell.
