Those of you lying awake at night next to complete strangers wondering who Ashley Madison, the dating site for married folks, would endorse for president—wonder no more. It's Newt Gingrich, a self-proclaimed expert on domestic affairs, now appearing on a billboard in Pennsylvania that reads, "Faithful Republican, Unfaithful Husband,"  and welcoming all to "the AshleyMadison.com era." Site founder Noel Biderman explains: "Now that Newt is the leading contender in the race for the GOP nomination, we felt compelled to make a point to illustrate how times have changed when a serial divorcee/adulterer is capturing the hearts of the American people." (Why Pennsylvania? Biderman says it's the only state where Ashley Madison's membership increased this month. I guess Virginia is for lovers, Pennsylvania is for cheaters and in Maryland you'll just catch crabs.) Gingrich hasn't responded yet, but when he does, he should send candy, flowers and a key to a room at the Holiday Inn. Actually, I find Newt an odd choice, as he recently flip-flopped on the issue by taking a "no adultery" pledge.  The group initially romanced Herman Cain,  and even offered him a $400,000 job. Leave it to Ashley Madison to throw over its first love and play the field. Back in April, Ashley was all hot for the Kennedys.  I guess this crew will jump into bed with just about anyone.
