Fox News and Talk Radio would furiously defend him as a great patriot speaking truth to power. He would almost certainly be invited to speak at the next three CPACs. And there are plenty of places around the country where he could win a congressional seat.
Do you think even the racial context of the comment would fly in even heavily Republican areas? Am I underestimating the racism of many voters in this country or could this be realistic scenario in which such a candidate could be elected into congress?
Yes and yes. Just look at how Fox News has covered Ferguson and Black Lives Matter. Also look at what's happened with Phil Robertson from Duck Dynasty since his interview, becoming something of a regular at conservative and Republican events - his remarks on gays got all the attention due to the crude language he used, but his remarks on race were far more odious.
