A new Marist Poll in New York shows that Rudy Giuliani (D) would a formidable challenger to Sen. Kirsten Gillibrand (D-NY) and now holds a 14 point lead, 54% to 40%.
Key finding: "Even one-third of Democrats report they would back the Republican challenger, and Giuliani runs competitively against Gillibrand in overwhelmingly Democratic New York City."
Reports suggest Giuliani has told confidants that he will likely run for Senate and not Govenor next year.
Update: Giuliani aides now deny he's made a decision to run for Senate.
