The unity will last through Inauguration Day, as he give a “speech for the ages” which the news media will have thrills up their legs about. It’s very predictable. The media will swoon over the speech, and Joe calling for unity in that speech, and even any policy which Joe may touch on in that speech.
The media will wax poetic about how this peaceful transfer of power is an American tradition going back over 200 years, yadda yadda yadda. We will be told how historic this is, with Kamala as the first woman vice-president, yadda, yadda, yadda.
He won’t make it to 1/20/21. He will have an “accident” and Kamila will be sworn in as Fuheress.
