In Pennsylvania, Pat Toomey is running against Arlen Specter in the Republican Senatorial primary. Toomey is a hard-right conservative who currently serves in the House of Representatives. Specter is a center-conservative Senator who fails many hard-right litmus tests, most noticably by being one of the handful of prominent Republicans who supports abortion rights. Both Bush and Rick Santorum have endorsed Specter.
This is one of those wedge issues — Bush’s hard-right supporters can’t be pleased that he endorsed someone so centrist, particularly since he differs with the Republican Party on such a hot button issue. Run, Roy, run!
