Bernie had a ceiling of like 30% among democrats. Biden smoked Bernie when it was just those two remaining. Democrat voters clearly chose Joe over Bernie. As to democrat leadership seemingly not caring about the nominee, it is entirely possible that they don’t want to ‘waste’ a good candidate. The incumbent President is almost always reelected. (Only three incumbents lost since wwII)
