It seems to me leftism is a feature everywhere among the inner city people in the Western world. The only major exception seems to be Sydney Australia, where moderates tend to dominate. I have no doubt Kerry will scoop up votes over here - if any US Democrat candidates happen to lose out votes to conservatives in Manhattan the sun would have risen from the West first! ;-)
But back to NYC. I had a chance to visit your city back in 1999 and the business districts and the PATH train reminded me a lot of my original hometown Hong Kong (heck, even the rudeness is a lot like HK, except New York usually English is spoken of course). All in all I quite enjoyed it because I knew New York had turned around from the really sorry state back in the 1970s/early 1980s - although I confess Hong Kong has really new infrastructure. Of course 9/11 is...sigh. Probably won't go back for another visit until every rebuilding has finished.
I'm still amazed how Guiliani got elected - from my impression New Yorkers back then would rather die than abandon the then-fashionable soft appeasement of crimes. Maybe New York has now entered the post-liberal (or at least moderate) era and we will see a lot of ridiculous socialist policies repealed day by day. We can only pray. (I always found America is a bit like two extremes - yes the conservatives are really good, but when you get to bureaucrats or socialism implemented, they could get monstrous in big cities - an interesting phenomenon)
Thanks for the comments on subway - I think the state it was in when I visited NYC (1999) was quite good. And I said this after I grew up with Hong Kong's MTR ( http://www.mtr.com.hk ) and trains ( http:www.kcr.com.hk )! Although I think stations could be cleaner, but then it is light years ahead of the suburban rail here in Auckland.
