This was a politically dumb thing for Obama to say. Republicans, if they’re smart which they aren’t, can use this to nationalize the election in November. But, just another great opportunity they will probably fritter away.
UPDATE: Former Obama advisor David Axelrod says it was a mistake for Obama to say his polices are on the ballot. Will Republicans seize this opportunity? Well, judging by their past history I doubt it. Some are, though. But will they do it skillfully? No way.
