Usage and Grammar

Q. Hello, I saw Barack Obama speak and he seemed to make a grammar error. I was wondering if I was missing something. He said, “President and Mrs. Bush invited Michelle and I to come to the White House.” Another time he said, “It was for Michelle and I.” Shouldn’t it be “Michelle and me”? My husband thinks I’m crazy to spend my time thinking about things like this, but it bothers me.

A. You’re right—I’ve heard Obama say that myself. But you have to feel for the guy. I’d wager my job that he knows the correct grammar. But he knows that hardly anyone uses it and that if he does, he’ll sound either incorrect or “elitist.” What’s a pol to do?
