No. Rendell is going to have a tough election.
I don't recall Rendell's endorsement of Alito being "reluctant" as AP reports. Rendell's wife is also a judge on the 3rd Circuit, who's served with Alito for years now .. and, presumably, was one of the seven 3rd Circ. judges who came to testify in support of Alito. And, yes, Lynn Swann, the Steeler Great, is running against Rendell, so he will have a tough race (Swann ahead in most recent polls).
