Gov. Andrew Cuomo will headline a fund-raiser in New York City tomorrow for the House Majority PAC, the Super PAC dedicated to helping the Democrats in their quest to win back control of the chamber.

A Democratic source familiar with the event says it will be held at a private residence. Cuomo, Rep. Steve Israel, a Long Island congressman who heads up the DCCC, and House Minority Leader Nancy Pelosi will be on hand. Organizers hope the event will raise a cool $1 million.

Pelosi specifically requested the popular governor’s assistance, given the number of competitive House races in New York, according to my source.

Following his Red Room cabinet meeting earlier today, Cuomo confirmed he’s now assisting both Pelosi and the Obama campaign, although he doesn’t know yet which swing state he’ll be visiting on the president’s behalf.

“I am helping in with Congressional races. I’m helping fundraise for Congressional races. I’m helping Nancy Pelosi, for example, fundraise,” Cuomo told reporters.

“So, I’m doing that not because the Obama campaign has asked me to do it. It’s something that I wanted to do. I’m assuming that the Obama campaign is going to want me to undertake activities to help him with those, getting the votes out, because it’s getting very close and I don’t think it’s going to be a lot of tangential work. It’s going to be getting a lot of people to get out and pull the lever for President Obama.”

It’s a little ironic that Cuomo is now getting involved to assist the House Democrats in their higher-than-usual number of competitive races in New York. The number of contested races might have been lower had the Legislature redrawn the House lines instead of a judge. But Cuomo declined to get involved to try to settle the differences between the Senate and Assembly – even after Pelosi asked him to.

House Majority PAC is currently active in five New York House districts: NY-1 (Rep. Tim Bishop vs. Randy Altschuler), NY-18 (Sean Patrick Maloney vs. Rep. Nan Hayworth), NY-19 (Julian Schreibman vs. Rep. Chris Gibson), NY-24 (former Rep. Dan Maffei vs. Rep. Ann Marie Buerkle), and NY-27 (Rep. Kathy Hochul vs. former Erie County Executive Chris Collins).

The PAC is planning to spend about $2.2 million overall, with its biggest investment to date – $1 million – going toward assisting Maloney/attacking Hayworth in the Hudson Valley’s redrawn NY-18.
