@blatham,
Frum?
He's smart and writes fairly well but he is devoid of principles. A pretty vile character.
Many people have shifted from one side of the political spectrum to the other. Some like David Horowitz because they have seen the light and others like Frum and Adrianna Huffington because they saw the side of the bread that was buttered.
Yesterday I heard the vermin of a man on NPR declaring the most outrageous things about Trump that he could not possibly know to be true.
At this point, I wouldn't be surprised if you linked us to a quote by David Duke criticizing Trump with an accompanying comment of "Important stuff here!"
