Negotiating the rezoning process was largely a political triumph. Same for the bike lanes, parks, and redevelopment of public land. Bloomberg has had a very visible impact on the city - but even more importantly most of his reforms are a ratchet. Plenty of politicians implement a program for a time, they can later be undone. Bloomberg has done a bunch things that can't be undone. There is no way to put the bike share program or more park land back in the bottle now.
