I was at a Montgomery conference in San Francisco years ago and
Bloomberg was the keynote speaker. During his speech he worked in
that it was likely he "was the only Democrat in the room." I didn't
think the timing was right to leap to my feet but was damned
impressed.
He ran as a Republican because of the logjam of Democrats already
positioned for endorsements. It was easy for him to run as a
Republican in NY city since there existed such a dearth of intelligent
Republicans that could begin to hold a candle to Bloomberg.
Bloomberg may dress himself in Republican garb but he's a Dem at
heart.
