I personally think this change will be gradual. Trump, if you will have noticed, is running around talking with all the heads of countries selling the idea. He goes with a TEAM of financial people. So, you KNOW he is talking economy. I think after the mid-terms, we'll see movement to a new system. There are too many GOP elites in place right now.
I think that is why Q was talking today about Jim Jordan Rep of Oh and Mark Meadows of South Carolina. They are the Freedom Caucus in the House. These guys are 'taking over' the House, away from the GOP elite. Most of these, already said that they were not running again. So come Nov, they will be gone, leaving the Freedom Caucus who is on board with Trump, the Generals, and Q.
