In his statement, Specter thanked Cornyn and McConnell for their “forbearance.” Here’s Cornyn’s statement (bolded in the original release):

“Senator Specter’s decision today represents the height of political self-preservation. While this presents a short-term disappointment, voters next year will have a clear choice to cast their ballots for a potentially unbridled Democrat super-majority versus the system of checks-and-balances that Americans deserve.”
