Bloomberg's rules

New York Mayor Michael Bloomberg

I always wonder what makes a rich man write a book. When a rich politician writes a book, one has a strong suspicion that it's not for the money. New York Mayor Michael Bloomberg, the pride of Medford Square, has a contract for a book called "Do the Hard Things First (and Other Bloomberg Rules for Business and Politics)," to be published by Vaguard Press later this year. The deal was reported by the Wall Street Journal.

Hizzoner said there's no advance and the profits, if any, will be donated to the World Trade Center Memorial Foundation. He declined to run for president when his name was mentioned in the current campaign. The 66-year-old pol has been both Democrat and Republican, and now is an independent.

All of which makes it hard to figure his motives, unless it's to keep his name and voice and ideas before the public -- just in case there's a draft-Bloomberg movement before November.
