This isn't intended to be truthful. It's strategic rhetoric intended to push Biden into moving further right. Their goal is to move Democrats right so they too can move right.
I think the short term goal is to just push the nominee more to the right so that he'll be competing with the republican on their own terf. And if people have a choice between the real deal conservative vs the bland centrist friendly one, they'll choose the actual conservative--the republican. And by pushing Biden to the right they help themselves by making Biden even more disgusting to leftist voters than they'll stay home.
