I’m not sure I get this criticism, given the source. Pat Roberston endorsed Rudy Giuliani, who is inarguably less conservative than John McCain, and who carries several tons more of personal baggage than McCain. That endorsement went nowhere, but a reasonable fallback for Robertson would be the more conservative McCain. As for the macho argument that Robertson puts up, isn’t that essentially what the left tried to bludgeon Reagan with — that he was too crazy to be put in charge of the leadership of the free world? How’d that work out?
There are plenty of reasons for a conservative to oppose McCain. His temper might make it difficult for him to unite the party, but that’s not the argument that Robertson makes. He just says that McCain might let his machismo get us into wars. I don’t think that’s true, but I don’t mind if our enemies do think it’s true.
