I noticed the same thing on Breitbart. Don't get me wrong, there are still the typical knuckle-draggers posting there, but the mood about Trump and his promise of America First and not getting involved in foreign activities has definitely had an impact there as well. 

As more and more of his promises get left behind, I think you will see even more become disenchanted with him as well. 

The ONE big hope he has is IF he can bring jobs (only if permanent good paying) back. We will have to see how that one works out. It SHOULD have been the first thing he worked on.
