Sen. Kirsten Gillibrand (D-NY) raised in excess of $2.3 million since her Senate appointment.

I think that she is doing this to fend off/scare off a primary challenge from Rep. Carolyn McCarthy (D-NY-04), who is now polling ahead of her 33%-29% in the latest polls, though she is still below the magic 50% safe number for incumbents against Peter King, leading 40%-28% in the general too.

I think that Gillibrand will end up moving to the left over the next few months in order to fend of McCarthy, but time will tell.
