Dan Senor is the latest Republican to look at a bid against Sen. Kirsten Gillibrand (D-N.Y.).
The New York Post says Senor has been making the rounds, meeting with state GOP Chairman Ed Cox, political activists and fundraisers.
Of course, Senor, even more than former Bush administration official Rob Portman, will have to deal with the "Bush adviser" label. It's easier for Portman to talk his way out of that one, and Senor would be running in a more anti-Bush state.
Gillibrand stands out as the one Democratic incumbent against whom the GOP has struggled to field a challenger thus far.
Bruce Blakeman is the only official GOP candidate, and he's holding a fundraiser at NRSC headquarters this week. New York Daily News publisher Mort Zuckerman is also weighing a bid.
