Obviously, it will help McCain in the long term to work to bring the Republican party together as soon as possible. But there is something a little lunatic in the demand that he essentially overhaul his campaign approach now, right this second. Because the thing is, he’s winning with his current strategy. It’s the other guys — the moderate-turned-movement-conservative and the Southern-Christian — who aren’t winning. He has three times as many delegates as Mitt Romney. No rational person would overhaul what’s working. There’s an echo chamber at work among those who dislike McCain — they hear and see and read mostly things with which they agree, and they therefore think that everyone agrees with them and that McCain must be in trouble.  McCain knows trouble. He was in deep trouble last year, when he fired most of his staff and was left for dead by most of the political cognoscenti. Winning 600 delegates in a single night isn’t trouble. It’s the opposite of trouble.
