You need to deploy a certain kind of musical rhythm to deliver a good speech. Especially if you’re reading off a prompter. Some have a natural gift (Bill Clinton, Barack Obama) and some need to learn it, and others can’t find the groove even with years of practice. All to say that Donald Trump‘s delivery last night was flat and robotic. No spirit, no energy, no relish. And it went on for what, 70 minutes or so? The speech itself was the usual bullshit, but he would’ve done much better if he’d winged it.
