Whether you're more a fan of 538 or Nate's aggregator, the idea is that Trump is still in a band between 48ish-75%. Which last I checked, isn't 99%. Yet his campaign is acting like it's 99%.
Reminds me of the old Fritz Hollings quote: "There's only two ways to run for public office: one is unopposed, the other is scared." I think he's favored to win at this point, but his campaign is running a little overconfident right now IMO
