Democratic Primaries

That's true. The vast majority or Sanders supporters probably already know they will vote for Biden. *Especially* the Sanders supporters on DU, where that number is probably very near 100%.

Nevertheless, a psychological battering down or belittling by Biden supporters can affect enthusiasm. And while an enthusiastic vote may count exactly the same as an unenthusiastic one, there could be differences in things like how much they talk Biden up among their friends, whether they contribute $ to the campaign, whether they volunteer, etc.

I've seen lots of posts over the year of people who said that, even though they would hold their noses and vote for Sanders in the general if it came to that, they would NEVER support him in the primary simply because they can't stand the attitudes they've seen from his supporters. You think that shoe can't be worn on the other foot?

So let me turn this around: With Biden the presumptive nominee, what *positive* impact do you think your OP has? Does it provide any useful info to anyone? Does it make anyone feel better about our candidate? Did you think anyone here actually had the answers to the questions you posed? If you were genuinely curious about what people here thought those answers would be, fine, but you still could have asked the questions (perhaps made it a DU poll) without loaded terms like "slink" -- but since that's not the route you chose, it looks more like you don't really care about those answers, but just felt like putting up another "let's bitch about Bernie" post. So the question is, why? In what way is that productive or useful to anyone?

If you feel you must express solidarity with other Bernie-haters, maybe at least post in the Biden group, where you can do the same venting without ticking off people who it would be better to have as allies.

IMO.
