Unfortunately, this likely won't be the case. Millennials I know who harbor desires to run for president some day are so boring, that they have nothing incriminating on their social media accounts to even be worried about. They will just use this kind of information against their potential and actual competitors. I suspect that it will take at least another generation before we are willing to accept a candidate whose colorful youth comes to light before they're elected.

Obama was a member of the "choom gang" and had various other shenanigans well-documented in his youth. Didn't prevent him from becoming the senator and then the president. I think you overestimating the interest of the public to Facebook. Of course if there were something more serious that a bunch of embarrassing selfies, that'd be different business, but that what we want to happen, don't we?
