Now that you mention it, it wouldn't surprise me. I can't fathom why Specter would attempt to talk Craig into staying after he held the big press conference announcing his intent to resign. The Governor has picked the replacement. There is simply no point in trying to reverse the process at this stage of the game. Craig would have absolutely ZERO credibility left. And the GOP's credibility would suffer as well.
Trying to fight this mess would simply mean delving deeper into the lurid details of Craigs personal life, and keeping this scandal on page one day after day. "Is he (gay)... or isn't he...?". The GOP needs that like they need Mark Foley running for re-election.
Good Lord, just let sleeping dogs lie.
