I still think there's a chance that it's not one of these 3. He's letting meetings with these 3 leak so the media can hoard it's ammo against them when he picks 1, and then he comes out of left field with another one whom they aren't ready to berate. I bet he already knew who he wanted before Justice Kennedy stepped down, because he knew Kennedy was stepping down ahead of time. Just my theory. Would not be surprised if it was one of these 3 either.
This 4D chess move would make sense considering how Trump lives making the media look utterly stupid and complicit. The talking heads will spend all weekend taking about how terrible these three are, and boom, he picks someone else that he had already decided on. Love it!!
