From CQ Politics:

The Draft Kudlow Committee, which is gathering signatures to encourage the conservative economist to run, added former New York Conservative Party State Chairman and co-founder Serphin Maltese to its ranks Tuesday. Maltese joind Buffalo-based PR consultant Michael Caputo and Dr. David Tukey, a former McCain-Palin deputy regional campaign manager based in New York City.
And John Lakian, the group’s new finance chair, told the New York Daily News on Friday that Kudlow is “80 or 90 percent” likely to take on the state’s senior senator.
Lakian also said that there’s no rush for Kudlow to declare his intentions, saying he could wait as late as April to get into the race.
