Why is Specter there ? Because the Democrats haven’t run a serious, first-tier candidate against him since 1980 (1986 they thought they had one with the Communist Congressman and Castro apologist Bob Edgar, but he was a bust, since he scared a lot of Conservatives into voting for Specter. Had the Dems run SoCon Donald Bailey, State Auditor and a former Congressman, the race would’ve been far tougher for Specter). The Democrats had to FLOOD the 2004 Senate primary to prevent Toomey from finally taking down the Senator from Scotland.
I don’t think you will be electing any GOP in PA...when Spector goes, I fear a Dem will replace him. Look at the Presidential election. It was not even close. McCain and Palin lived in PA for weeks before the election.
