They didn't have anything to do with his failings.
Those that failed the Republican Party were evangelicals that picked Bush in the primaries simply because he was an evangelical.
Well it should be obvious by now that being an evangelical doesn't necessarily make a person a good president. Yet here were are talking about Palin in 2012 all because the evangelicals think shes just swell. And yet again, that's all they seem to care about. Palin is a nice person. Sure. But she's just as shallow as Bush. She'd be another disaster.
As of now, a better candidate has not stepped forward.
