I DIDN’T HEAR IT, but I’m told that Rush Limbaugh was quoting Ann Althouse’s theory on why Obama supporters chose to emphasize Obama’s poor performance rather than Romney’s good one:

Here’s why they did it. Romney was so much better than Obama. Romney was vigorous, vividly in command of the facts, principles of economics, free-market ideology. Like Obama, he had a strategy to appeal to moderates, and he jumped into the moderate ground and occupied it — stunningly — with modesty and charm. He radiated competence and readiness to work for us. There he stood, the brilliant candidate, who wants only to help us, knows how to help us, and deeply, passionately cares that we need help. Wow.

Don’t let that be the story! Don’t look at that! Look at pathetic woeful Obama. He was off his game. That’s not good for Obama — as his drop in the polls shows — but it was better than the alternative: talking about how Romney dramatically topped the President — the President, who came to the debate with all the gravitas of the presidency and all the knowledge and understanding that he has through working as the President these last 4 years.

The meme The Bad Obama was — colluding pundits decided — preferable to The Great Romney.

Makes sense.
