President Obama, may I give you some campaign advice?

I'm independent, moderate, and pragmatic, and I voted for you in 2008 because I thought I saw those qualities in you. I still see those qualities in you, but the you that has those qualities is one of two Obamas, and the other Obama — Radical Lefty Obama — is a person I will not vote for.

I think you alternate between these 2 personas, and I sense that you've done it for so long that it feels normal and comfortable to you, but I want to urge you to pack up Radical Lefty Obama and stow him away with the rest of your Harvard Law School memorabilia. I know you — the Moderate Obama — have impressed some very useful people over the years by parading about as Radical Lefty Obama.

Like yesterday, you gave that Republicans-are-extremists speech, and the New York Times loved it:

Mr. Obama provided a powerful signal on Tuesday that he intends to make this election about the Republican Party’s failure to confront, what he called, “the defining issue of our time”: restoring a sense of economic security while giving everyone a fair shot, rather than enabling only a shrinking number of people to do exceedingly well. His remarks promise a tough-minded campaign that will call extremism and dishonesty by name.

Notice how, in expressing its love, the NYT portrayed Radical Lefty Obama as Moderate Obama. It's Moderate Obama that American voters find so appealing. You don't need all that left-wing economics and race-and-gender demagoguery. I think what people like about you — you, who are famously, sublimely likeable — is the normal person who seems to be in harmony with everyone. We — many of us — voted for you because you seemed to offer to bring us together, to end the rancor.

Be that Obama.

Note to Mitt Romney: If Obama doesn't want to be that Obama, you can be that guy.
