I (and, to be fair, others) have observed that the fundamental premise of the Trump campaign is that he is a winner. The evidence most often used to support this comes from polling numbers. Ergo, when one of his opponents challenges him on a policy issue, his standard response is to swat the matter away by calling the challenger a loser, and by citing the most recent polls to prove it.
I honestly can’t remember anyone ever campaigning like this, but in economic terms, what Trump is attempting to do is to create a bubble, and we all know from recent experience how that is likely to end. “Vote for me because lots of other people have said they will vote for me” is not a message that will survive repeated defeats.
At least it isn’t a Ponzi scheme, which was my initial reaction.
