I am not going to give Trump credit for a good campaign just because he won. I think he won in spite of his campaign, not because of it. I am only talking about the public side, not whatever his campaign did behind the scenes. It looks like they did well getting their voters to vote. I think Harris ran a much better campaign.
Let’s look at the Trump campaign:
He was sometimes several hours late for his rallies.
He told lies over and over
He said terrible things about Harris
He complimented Hitler
He staged an illegal political photo op at Arlington Cemetery
He made racist comments
He called his opponents “vermin” and “the enemy within”
He lost the debate and said dumb stuff like “eating dogs and cats”
He hasn’t always paid for the places he held rallies in
He often used music without the permission of the artists
He was sometimes rambling and incoherent
He hampered relief efforts in North Carolina by lying about them
He said there was election fraud without any basis for his lie
He had 39 minutes at one rally where he didn’t speak
He praised fictional killer Hannibal Lecter
He appeared to mime giving a blow job to a malfunctioning microphone
I don’t think this constitutes a good campaign.
