But an educated speaker is expected to keep his pronouns in line. Here, then, is a tip, Mr. President. Nobody chooses the wrong pronoun when it’s standing on its own. If you’re tempted to say “for Michelle and I” in tonight’s speech, just mentally omit Michelle (sorry, Mrs. Obama), and you’ll get it right. And no one will get on your case.
A) The tip is hard to apply when it's "correcting"
between Michelle and I.
Between me makes no sense whatsoever.
2) I hear this "error" more from the educated than from the uneducated.
