I thought the act was wearing thin years ago and was wrong, but now Trump really does seem to be becoming monotonous, as I wrote for Politico today:

The rallies, once an innovation and still his campaign signature, long ago fell into a groove of familiarity — the stilted reading of scripted remarks off the teleprompter, interrupted by spontaneous riffs and ridicule of his enemies.
Perhaps, by now, the terms of abuse have become such timeless classics that fans would be disappointed not to experience them live, a little like going to a Beach Boys concert anytime over the last half-century and not hearing “California Girls.”
Yet you could have heard the same lines at any Trump rally at any place on any occasion over the last several years. The media is still Fake News. MSNBC is still MSDNC. Adam Schiff is still shifty and Chuck Todd still sleepy.
And, as you might have heard, Chris Wallace always wanted to be like his father Mike of “60 Minutes” fame, but sadly didn’t have the talent.
One can only conclude from this that the glory days of Trump nicknames are over. Perhaps there will be a renewed burst of creativity if he runs again in 2024, but for now, he’s content to rely on his greatest hits.
