Harris will find it difficult to stop criticizing Trump and start criticizing Pence, which is an index of how noisome Trump is because Pence, whose political career would be long dead if Trump hadn't required him to deliver Evangelicals to him. is no one's idea of a prize (except perhaps among Evangelicals).
Pence will speak in calm, measured tones as if he were a normal VP rather than a man whose public career had been resuscitated to vice-preside over an unprecedented dumpster fire of an administration, but as the minutes pass he'll become increasingly flustered by sharing the stage with a beautiful woman who's not his wife.
