Jimmy Carter for President 2020?

Isn’t this a sure sign that a politician is running for office?

All kinds of things can run through the heads of people buckling themselves into an airline seat with even a remote understanding of current high-altitude events.

But passengers on a Delta flight from the D.C. area to Atlanta got a surprise that was welcome and charming: a grinning, nonagenarian, bolo-tie-wearing former president who ambled down the aisle, apparently shaking every single passenger’s hand.

The video clip of Jimmy Carter was taken by passenger James Parker Sheffield. He’s the one in the video who says “What a pleasure. Thank you,” in five words summing up the collective thoughts of the Internet since it was tweeted on Thursday.

So is he running in 2020??
