If he was truly into cutting taxes, he would have gone along with it. You just undermined your entire position.
I repeat.:
If you do some research you'll understand that he was doing his job as Mayor of NYC. The state government in Albany sprung this on him just as he was about to cut taxes in the city. So think about it. They were going to take away revenue from the area he governed. It was a political battle between the city and the state and does not reflect his opposition to tax cuts but rather his advocacy for the people he represents.
