The New York Daily News: Rep. Carolyn Maloney has decided to take on Sen. Kirsten Gillibrand in the 2010 Democratic primary.

That primary will have huge ramifications for gun owners, as one of Maloney’s big issues is gun control, while Gillibrand has been generally pro-Second Amendment in Congress. (Eh, scratch that; while she was that way in the House, I’m told that since she joined the Senate her voting record suggests another remake of Invasion of the Body Snatchers.)

Rep. Peter King, who represents part of Long Island, is the likely Republican candidate.

UPDATE: Eh, maybe not on King; apparently a slot on the House Select Committee on Intelligence is enough to make him lose interest in the Senate.
