Though it’s a safe bet that Newt Gingrich won’t win the Republican nomination, he has done well enough in the primaries to spare himself the embarrassment of abject failure. He has not made a fool of himself — or, at least, no more a fool than he does in the regular course of pontificating, lecturing and hectoring.
He will leave the campaign with his legacy intact. And what a legacy it is. Gingrich has done as much as any single person to divide the country, destroy civil discourse and promote incendiary rhetoric.
