I don't recall the Clinton supporters expressing such visceral distaste for Obama as the Sanders supporters express for Clinton.
You have stake in this game. You want Sanders supporters to come around to Clinton. I don't want to see her as president so I hope they don't but I don't think they will, ultimately, make a difference. She will win or lose with or without them.
I also don't want Trump to be president so I'm sort of screwed this year. My desires are not advanced if all Sanders supporters stay home. One way or the other someone very bad for this nation is going to become president.
If you go on and on about how corrupt and despicable a candidate is and then at the last minute you change your mind and support her because Bernie has recognized on which side of the political bread his butter is spread, then you are a drone, a ewe, a castrated ram, a person without principles.
BTW - I suggest you dial it back a bit with your Clinton fervor. At best you could persuade a half dozen Berners to vote for her and in the mean time you are pissing a lot of people off.
