The premise of the Onion's "report" is perhaps true at this very moment: The embarrassing shit basically everybody under the age of 35 has posted on Facebook would probably make them unelectable today, if a political opposition research team got a hold of their profile.
But norms change. Yesterday's career-killing scandal is today's single-day news blip, reported and basically forgotten within the same 24-hour span. And if everybody's had their photos taken with a six-foot bong named Goliath or videos doing keg stands posted all the over internet, that's not unacceptable behavior, it's simply normal.
"I'm just like you, I grew up on the internet" will be the new "I grew up in a small town." It's the people who don't have a Facebook profile that are gonna be the weirdos — if you don't have an internet presence, you're clearly the one with something to hide.
And I can't wait to see who the presidential candidates of 2040 really are.
