On the other hand, there’s David Frum’s take:
The Specter defection is too severe a catastrophe to qualify as a “wake-up call.” His defection is the thing we needed the wake-up call to warn us against! For a long time, the loudest and most powerful voices in the conservative world have told us that people like Specter aren’t real Republicans – that they don’t belong in the party. Now he’s gone, and with him the last Republican leverage within any of the elected branches of government.
For years, many in the conservative world have wished for an ideologically purer GOP. Their wish has been granted. Happy?
