All of the Biden supporters telling Sanders supporters how wrong Sanders is or was and telling them that they have no choice but to vote for Biden are basically helping to garuantee that Biden looses their vote. They want Biden to earn their vote, and telling them to hold their nose and vote for Biden will make them want to punch the nose of the person talking.
Bernie signed a pledge to support the primary winner along with 22 other candidates. See the first link to view the pledge. All of the other candidates have gracefully accepted their loss and will support Biden. So what's the problem? Why do you think it's ok for Bernie to make demands when none of the other candidates have? See the second link for a history of the primary candidates' performances. Biden will win by more than 20 percent.
FYI... I have not seen one supporter of any other candidate whining about the outcome of the primary.
Wow! You've almost convinced me. Just keep going . . .
@towkneed I respect your right to vote for whoever you want. I also respect your right to grudge the rest of your life when things don't go your way... But good luck with that!
@towkneed Bernie Sanders just endorsed Joe Biden. 4/13/2020
@kensmile4u Saw that this morning. Thanks! And thanks for wishing me luck! You too!
