Then there's the wife trifecta. No one in American public life, other than perhaps their kindred spirit Newt Gingrich, has ever mastered the art of a bad divorce like Rudy and Donald, carrying on as if spousal humiliation was the point.

Ask the kids. When Trump married mistress Marla Maples nearly four years after he walked out on Ivana, the three convention stars, Don Jr., Ivanka and Eric, didn't show up. Andrew and Caroline Giuliani made strained appearances at Rudy's 2003 wedding to Judi Nathan, but in 2007, both distanced themselves from their father's presidential pursuit, with Caroline Facebooking her preference for Obama, as close to the ex-mayor's heart as she could plunge the dagger.

Rudy's wife Donna found out he wanted a divorce when he announced it on TV, just as Marla had a couple of years before. Rudy then chose Mother's Day to alert the press that he would be having dinner with his new love and led the cameras on a 10-block walk with her after dinner, kissing her goodbye while his wife and kids simmered. His divorce lawyer declared "we're going to have to pry her off the chandeliers to get her out of" Gracie Mansion.
