The appearance of President Trump on CNN on Thursday was a turning point of modern American political history. The dream-world of dirty tricks and self-delusion in which the Democrats and other Trump-haters prevalent in the national political press and among the Bush-McCain-Romney-McConnell Republicans, was blown up and sunk like the outer ships on Battleship Row at Pearl Harbor. The questioner, Kaitlan Collins, elegant, articulate, and argumentative, with impeccable anti-Trump credentials going back to rude dust-ups at Trump presidential press conferences, was rolled over by her guest as if by an Abrams tank liberating the Donbas.
