Patricia T. O'Conner and Stewart Kellerman, in today's New York Times:
Since his election, the president has been roundly criticized by bloggers for using "I" instead of "me" in phrases like "a very personal decision for Michelle and I" or "the main disagreement with John and I" or "graciously invited Michelle and I."Given the state of presidential English (aka "American") between 2001 and 2009, it seems a bit absurd to criticize the new president for a single pronoun problem. I too though would like to hear "me."
I've wondered: might Obama's "I" be intended to avert perceptions of error that might follow from the proper use of "me"? No, I don't really think so either. My guess is that the "I" is a matter of long-standing habit, which also explains why I still say "stove" for "oven."
