He was a dem.That's wrong at the most basic level.
He ran for mayor as a Republican in 2001 and served his first two terms as a Republican before switching to an Independent for his third term.
Then a republican.
Then an independent.
Then a dem again.
People can switch parties. That's not the criticism Bernie faces.
It's that he want to criticize and reform a party he's nor a part of. If he doesn't win the nom he will go back to being an independent and criticizing a dem party he only wants to be a part of to push his own presidential ambition and nothing else.
