It's more than foolish. These type of Bernie supporters would rather vote for someone who pushes America further from Bernie's vision, and making it harder to come back from (especially after one more Supreme Court pick). Even Bernie himself recognised this when he tried to urge his supporters to vote Hillary rather than let Trump win becuse he recognised very early the game plan from the Republicans. They've pretty much done everything he said they would do. Case in point; running up the debt by reducing tax then claiming they have to strip social security and healthcare to pay for it.

I don't think the type of Bernie supporter I quoted above even listen to what Bernie actually says. They just care he makes waves.
