Even a little superficial thought would show how insane this statement is. Is he the president of everything deplorable in the United States? Is he President of all the rapist, robbers, pedophiles, anarchists, sworn enemies of this country?
We compartmentalize and separate from us the worst in society that we deem unworthy of assimilating. It can be strongly argued that the President doesn't represent that, but repudiates it.
These witches represent the worst of the worst that our society is devolving into. They don't deserve a place at the table. The fact that we've given them a place indicates a grave sickness in our national identity.
For whatever reason, Cain’s campaign advisors believed this appearance would be helpful publicity. I’m inclined to agree, if not strongly. As long as Cain has the poise, being on a liberal show allows the customary viewers of such a show to see how a conservative reasoner addresses a liberal philosophy. Cain takes a risk, though, because if he bumbles the liberals will make mince meat of him.
