Sobran is also dissembling here by trying to insinuate that citizenship is as free from legal definition as religion is in the US. Any of us may change religious affiliation at will and the government has no power to require that we notify them. The same is not true of citizenship.
None of this really matters, since we have a President with very elastic scruples. Walker will skate because Bush hasn't the backbone to face the outcry that liberals would raise should he let the traitor be hanged as he so richly deserves.
