He made fun of the Biden-Harris appearance in an empty gymnasium where they kept socially distanced. US presidential campaigns, especially party conventions have, in my opinion, far too much pomp and pageantry, with large crowds cheering on cue and balloons and confetti and the like. I find those things utterly boring and never watch such events and I must say that I much prefer the current scaled-down, low-key format. I hope that even after the pandemic ends, we keep things the way they are now.
If we get rid of the glitz, then we will get to see more of the substance.
