Trump’s speech: first twenty minutes (about his personal recollection of the assassination) were excellent. The next twenty minutes (about the need for the country to unify) were fine. After that, unfocused, rambling; but, this is Trump’s style. He talks with his audience and makes a personal connection. Even though there’s a teleprompter, there’s a lot of spontaneity to this. But, Trump wasn’t at his best last night. Conclusion: disappointing.
But notice the difference: Biden can dissemble right before our eyes, and that’s fine. But, if Trump doesn’t hit a home run, that’s to be criticized.
Given what he’s gone through, relief at seeing our familiar DJT (though with the typical volume turned down a bit) seems more appropriate, rather than disappointment. But, your mileage may vary. And apparently has.
