Pennsylvania Dems Warn Against 'Cataclysmic' Sestak As Primary Heats Up


Meanwhile, Marc Ambinder reports that the White House and senior Democrats have become more nervous about Specter's chances: "A senior political strategist who is consulted by the White House puts the odds at '50/50.'"

The TPM Poll Average gives Specter a lead of 45.6%-35.2%. Specter's support has remained stable ever since last year, while Sestak's support has been slowly but surely climbing since February. The primary will be held in less than two weeks, on May 18.
