It's going to be interesting to see how the republicans handle passing it. They might just get it done quickly without fuss, as it's been a cornerstone of their policy. It may get dragged out as all the separate factions fight for their amendments,positions and deals, noting they only have a 2 seat majority in the senate. The longer it gets dragged out the higher the need for leadership from the White House to get it resolved.
So far the White House has leaked, temper tantrums when things don't go well, tweet storms in the middle of the night when he's angry and finishing the working week early to go to the country house. Does Trump have the leadership to get this through? Reality might set in, hes no longer running a family business mafia style where you get angry when things don't get done and fire people. Whole different ball game, is he up to it?
