He sounds like an interesting character, anyhow—thought not to be a conservative ideologue, Leder, who cofounded Sun Capital, has given money to a handful of Democrats. The Naked Philadelphian reports that Leder doesn't support "the social agenda of the Republican Party," which would make sense given the rumors about his hosting parties that prominently feature sexy dancing ladies. The NP also quoted a couple friends, one of whom clarified that "Marc was not in the pool" at the time of some specific reputed hanky-panky.
Another gave a more enabling response: "His wife cheats on him with the 23 year old tennis pro, so he lets off a little steam. Yet, he is the one that is vilified." (The ignominy.) Remember when everybody thought that Mitt Romney's Mormonism was going to give this campaign its weirdness element? Forget it—it's his money. And remember when everybody thought Romney was going to be boring on the campaign trail? Forget that, too, and enjoy the upper-class sitcom of manners this brouhaha is fast becoming—basically The Nanny, though I suppose the stakes are a little higher.
