i'd imagine that's something that they'd prepared in advance; like any sensible campaign would - I'm sure that Bernie has something prepared like that if he somehow manages to win 80% of the vote everywhere tonight and get a pledged delegate majority since that's sensible, its always good to be prepared for every eventuality. Was it a "scumbag move" that Romney had a transition website (and probably more things that we never saw) prepared in advance of the last Presidential election?
Speaking of Romney, he never prepared a concession speech. That kind of kills the argument that every Presidential campaign is prepared for every possibility.
Obvious lie was obvious. It's the type of thing candidates say to save face, like "I have no plans to be anybody's running mate", or "I'm staying in all the way until the convention!" the day before they drop out.
