There may be some gloating from hawks over the next week, or weeks. Much of it will be ugly; some of it will be unfair. There will be high-minded calls to refrain from such gloating. These calls should be resisted. When a lot of people get the big questions wrong, they deserve a few I-told-you-sos, and their future predictions should be taken more skeptically. That’s what happened to those supply-siders who made excessive claims about Clinton’s tax hike in 1993, and it’s what should happen now.
