On January 10, The Washington Post reported that Donald J. Trump passed a milestone that none of his predecessors is known to have attained: just short of the anniversary of his first year in office, he told his two thousandth lie. The path from the first lie to the two thousandth (and now beyond), a veritable Via Dolorosa of civic corruption, has been impossible for even the most resolute citizen to avoid. Trump is in our faces, and our brains, constantly. Yet the barrage is so unceasing that we can’t remember what he did and said last week, or sometimes even yesterday.
