It’s quite impossible to watch President Trump for any length of time and remain unperturbed. He possesses what psychoanalysts call “high transference valence”: the ability to provoke strong reactions in others. In fact, this appears to be a big part of his appeal. Love him or hate him, you have to look.
A better guess is that it’s the high degree of Donald Trump’s novelty that attracts attention.
