Mort Zuckerman (R) "is leaning against a run for Senate this November although he remains intrigued by the idea and could shift his thinking in the coming days," the Washington Post reports.
Perhaps he saw the new Marist poll which shows Sen. Kirsten Gillibrand (D-NY) crushing him in a general election match up.
Update: Zuckerman tells the New York Daily News, which he owns, that he will not run for U.S. Senate.
