But I admit I haven't paid that much attention till now. One would think there would be evidence of precedent.

2 months before the convention-

A speech for unity in Unity.

So you are telling me there were no week long meetings back then on how to endorse. I wasn't here then and I was always an Obama supporter, yet Hillary had class.

That woman has class!

going from memory here, too, so bear with me.

Going by past observations, and things which have been brought up about other losing candidates in the past. There is never supposed to be a quid pro quo for concession.

Thanks, DG!

is done per the usual protocol among Dem candidates.

This situation has never been a problem before. In old days, candidates were pretty much picked by party bosses. Few primaries. In last few elections, losing candidates have been gracious enough to concede without making any demands. But alas, not Bernie☹️

That was pretty awful and even though Carter was way ahead in delegates and popular votes, Kennedy refused to endorse and caused trouble at the convention by trying to change the rules at the last minute to get delegates to change their votes.

Kennedy's convention speech
http://www.americanrhetoric.com/speeches/tedkennedy1980dnc.htm

Just one example of an ugly end to a primary.

not exactly a ringing endorsement for Carter as much as a speech for all Democrats.

It was certainly not as bad as Christie's speech for Romney in 2012, though. LOL

but Kennedy was at a very dark period in his life then, much troubled by alcohol addiction, only finally helped by second wife Victoria Reggie (although one son disagrees with that take).

Also Kennedy, unlike any other Dem candidate ever, had had two brothers assassinated while in or seeking the Office of President and he didn't get along with President Carter generally. It was not so much his lack of endorsement as his primarying a sitting President in the first place that was problematic. He did finally endorse and campaign for Carter, but things like the 1980 Moscow Olympic Boycott and especially the ongoing Iran Hostage Crisis that ABC News - oh so helpfully - featured EVERY SINGLE NIGHT, were more determinative of the outcome of the 1980 election. See., e.g., https://en.wikipedia.org/wiki/Nightline#The_Iran_Crisis.E2.80.93America_Held_Hostage_.281979.29

I'm not excusing Kennedy's behavior so much as explaining why it may have happened.

And SBS is not now, never has been and never will be a Ted Kennedy.

Oh, you poor Bernie supporters...
