OK, the event amused Trump’s base. But Trump will get his mandate only by attacking the Demorats as a party (what they believe), not by attacking Harris personally. We don’t want voters rejecting Harris because of her lies but supporting the rest of the Democrat ticket downstream.
Guarantee he won some younger votes with that.
Trump must do both of those activities.
We don't have a world where most people decide who is to lead based on rational consideration of "issues".
