"I note, however, that the Left is not held to the same standard."
Not so. It has often been suggested that both Bill Clinton and George W. should do a little jail time to pay society back for their "youthful indiscretions".
Well, sure, it would be wrong to say that the Left is completely immune to criticism (Jimmy Carter especially comes to mind). But I don't think it is even arguable that the Left suffers much less criticism than the Right, at least by the national media, for similar behavior. For instance, do you actually imagine that a Republican president could have remained in office after it became public that he was having an affair with a 20 year old intern?
I understand that, to a Liberatarian, Republicans and Democrats look pretty much alike. But the fact remains that the press is very much a part of the Left, and thus an enemy of the Right, a fact which is reflected in their reporting.
BTW, I personally have strong libertarian leanings, and agree that our founding fathers did as well, although I believe it was called "liberalism" in those days.
