This is hilarious. Trump supporters mocking the other side for losing it. They always were losing it at the thought of Trump being president and that they knew Trump won't do a single shit he promised. Now that it has become a reality, they are merely pointing it out to the idiot supporters that they have been duped. But the Trump supporters have no recourse, have no explanation so they are just pointing and laughing that Trump haters are losing it. No - they are just, once again, saying that same thing they did before.
This guy is a liar and that he is just saying the catchy phrases to get in the office ("Build the wall", "Drain the swamp", "Make America great again"). Now is when we start to see it in front of our eyes that he won't do shit, Trump supporters have no way to defend that. The other side (people who didn't want Trump to win) already lost, now starts the long, slow and painful loss of Trump supporters when they realize that they got taken by a con man.
