I also wonder if this alleged “adult in the room” is simply trying to appease anti-Trump republicans so that they are still comfortable voting republican, on the basis that republicans are saving the day in the white house so don’t worry about Trump. The timing would make it seem that way. Until some republican comes out and make their opposition to Trump clear, as McCain did, it’s hard for me to see it as anything but republican self-aggrandizement without actual substance.
Interesting that both the right and left sides of the media are looking a bit askance at this statement.
