Definitely not asking from a political standpoint, but how could you dislike Bloomberg??? He rescued the city from certain financial ruin after 911 when the budget was so far in the red from a lack of corporate tax revenue and companies were relocating to jersey and ct? The city also enjoyed a green space/parkland renaissance and animated all of the water front with wonderful public spaces. I don't have the statistics in front of me, but I'm pretty sure the city had the lowest amount of crime in generations. Sure he had his own brash way of doing things, and he acted like he knew it all (which he did - the man's brilliant), but he was never the irrational bully that Giuliani enjoyed being and he had the people's best interest in mind.
As far as the low crime rate the country as a whole had a very low crime rate,with the exception of Chicago, and has seen all crime and violent crime especially dropping since the early 90's.
Rudy Guiliani like to take credit for this but crime dropped everywhere.
I think it had to do with the crack epidemic of the 80s. Anyone doing or selling crack were killing each other off at such a crazy rate, over 2000 murders a year back then. With all the crack dealers killing each other on street corners and the crack heads dying off there was a Darwinian effect on the criminal element.
Even the cops were using crackheads to kill crack dealers, like Larry Davis.
