Reporter's Note: President Obama’s party was probably not in much of a partying mood as the election returns came in last night. Perhaps he won’t be in much of a letter-reading mood either, but that won’t keep me from writing my daily missive to the White House.

Aides said Obama was not watching election returns.

Dear Mr. President,

Mathematics, as I’ve told you, was not my strong suit in school. I was intimidated by algebra, driven into fits by geometry, and the first time I even heard the word calculus I ran to my room with a box of Chicken-In-A-Biscuit, locked the door, and refused to come out until it was time for Gilligan’s Island.

I did, however, learn one important lesson about math and life; anytime something swings far away from average, whether left, right, up, or down, its next move will likely be back toward the center. Let’s say you had a magnificent day on the golf course and shot the best score of your life. Tomorrow, you may think that you will build on that success. But statistics tell us, you are more likely to play closer to your “average” and therefore, you will have a less stellar round. Likewise, if you have an unusually bad day, tomorrow you will probably do better. See?

It’s kind of counter-intuitive, but it is maddeningly reliable. As a result, every time I have a big win of some kind…on the job, at some hobby, or just a string of really great days…I accept that the natural trend will be for things to get worse. And if I have a really bad string of luck; hey, my spirits are great, because I know that soon things will looking up!

One year ago, the simple truth is, the landscape really could not have looked much better for you and your Party. I mean seriously, it was like Democratic Happy Hour coast to coast. What happened in the election last night was a measure of a lot of things; worry about the economy, concern about government spending; but it was also pure math.

Remember, when you are down, you are likely headed up. And when you are up, the next stop is probably down.

Call if you have a moment. As always, I’m around.

Regards,

Tom
