Bush’s former Secretary of Homeland Security, Tom Ridge, is considering a run for the Republican Senate nomination in his home state of Pennsylvania. Roll Call reports “Ridge’s moderate politics and national profile would make him a more viable candidate in the general election” against Arlen Specter, who recently switched to the Democratic Party because he feared that he would not be able to win the Republican primary. Several Democrats, including Rep. Joe Sestak (D-PA) and Pennsylvania Board of Education chair Joe Torsella, are considering competing against Specter in a primary. Specter has lined up the support of Gov. Ed Rendell (D-PA) and President Obama.
