I think it will be critical for Trump (and Vance) to use the Bully Pulpit during the first 100 days to communicated to the voters and public that elected him.
His message should be positive and he should state that he has been elected by the people to improve and change the situation in the USA and that he intends to do that for the benefit of all our citizens. He can tell protesters that they have a constitutional right to freedom of speech and to peaceful assembly. That he supports both, but that the vast majority of those polled said that the USA government was on the wrong track. He was elected to change that track.
He should find ways to get that message out to the public nearly every day of his first 100 days.
I thought Trump said that he will continue the Rallies.
