EXCERPT:
STELTER: "I think Trump world is jealous of the joy right now. There‘s so much anger coming from Trump’s speeches. Joy is real and it's important. People can make fun of it and say, 'Focus on the policy.' But if you ask political scientists and psychology professors, they‘ll tell you the emotions matter in politics. Sometimes they matter a lot more than the policies. And that‘s, I think, the big story this week."
