Via the New York Times:

The Senate on Wednesday turned aside the latest attempt by gun advocates to expand the rights of gun owners, narrowly voting down a provision that would have allowed gun owners with valid permits from one state to carry concealed weapons in other states.

The Amendment passed by 58 to 42, just two votes shy of a filibuster. Both New York Senators voted against the amendment, which aligns them with the Bloomberg administration; the mayor has been, frankly a fierce critic of the Amendment, leading a bipartisan group of mayors to in the now-successful defeat of the amendment in the Senate.

To quote the mayor via Ben Smith,

Saying that you will bring down crime by giving more people guns is just absurd, that’s the nicest way to put it. And, you know, only somebody who doesn’t- who plays- foot loose and fancy free with the facts and has an agenda would have the nerve to say something like that.
