CLINTON CLINCHES

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?

Well not really; since a concession speech is the total opposite to a victory announcement.  Campaigns generally prepare for victory, especially a campaign like the Clinton campaign who certainly knew that they'd get over the line tonight and ought to have expected that the networks would continually check for super delegate "pledges".  You can guarantee that Sanders had stuff prepared for wins in states that he didn't manage to win since that's a positive thing that you can sell; while losing something isn't something that a campaign isn't going to publicly try and sell.  The things planned for losing where you expected to win are going to be things that are a lot less visible; changes in strategy or tactics in upcoming contests, or simply dropping out if you think that you haven't got a hope left.

Besides concession speeches are generally a lot easier to write quickly than a victory speech while also generally being less important.  Things that you do in a concession speech: congratulate the winner and have some platitudes about working together on common goals, thank the voters, talk a little about the important issues that you campaigned on and perhaps say some nice things about your staff.  He may had not formally written a thing, but he definitely knew what to say when he needed to say it.  Besides if it got out that you had prepared a concession speech then that'd be spun in the media as you expecting to lose or some nonsense, and that's not going to look good for your campaign.
