I'm not sure I agree. While the Executive branch is far more covered in honey than they've ever been in the past (and will hopefully ever be in the future), ours is a largely stable democracy and we're facing no real threats. I think things could have gone seriously wrong under Kennedy, and I think things could have gone seriously wrong under Reagan, but I think both Kennedy and Reagan had enough experience in governance to get the job done and I think they were humble enough to surround themselves with people who at least had good, solid, intellectual reasons for acting the way they did. I think the United States in 2018 is the same as the United States in 2017, except that everyone is perfectly willing to second-guess the President because c'mon. It's the only sensible response.
