Some new polls show that junior Senator Kirsten Gillibrand may be vulnerable during her first election next year. According to the Observer, a Siena poll found that "I don't know" (35%) won out over Gillibrand (32%), who was followed by City Comptroller Bill Thompson (23%), while a Quinnipiac poll found that Thompson would beat Gillibrand 41-28 in a hypothetical primary. However, Quinnipiac's Maurice Carroll says, "Giuliani, who is pondering a Senate race, tops both of them" and Siena says Giuliani would beat Gillibrand 50-40.
