The moment that trump gets a single morsel of a victory related to territory expansion he will go on a victory tour which will seal his popularity for the rest of his presidency and movement. He might actually get panama or Greenland, which (Greenland especially) will have him lionized as a modern Regan by voters forever. Manifest Destiny never came close to dying.

I repeat, you will not like one bit what a 2nd constitutional convention will do. Kiss birthright citizenship goodbye. Embrace a constitutional ban on same sex marriage and late term abortions. You'll get far worse than this.
