You guys are way overanalyzing it. The point is to criticize Obama. He could have said the sky is blue and they would have responded that it's more of a periwinkle. The National Review and indeed the entire conservative moment is in crisis. We have the first left of center President who will leave office with positive feelings from the public since FDR. They must throw everything the can at this man and hope something sticks or else they are in serious trouble.
Well..let's not count our chickens before they hatch. There's still four more years for things to go wrong, but I think you're right. Obama is already a transformative figure. He's essentially shifted America to the left of many issues and conservatives will have to play catch up. They've lost their moral edge and they're pissed.
