Donald thanked Priebus over and over for the support, the ground game, and as a trusted advisor. It was very clear that the Trump trusted him more and more as the campaign progressed and Priebus worked hard and effectively to make it happen. He clearly helped Trump behind the scenes with the ground game and organization and several people who know acknowledged him for this (not just Trump).
Was not a fan of Priebus before because I detest the GOPe, but if he is good enough for Donald he is good enough for me (as if we have any choice). I will hold my criticism and give him a chance. He clearly impressed Donald and that is not easy to do by all accounts.
I’m not convinced Priebus is not a political opportunist who saw the handwriting on the wall and joined the team that would help his own political future.
