As I’ve said before, the D’s should have refused to allow him on their ballot long ago as he is NOT a D!
He’s a self avowed socialist, so either he is not a D and ineligible, or the D’s are admitting they are actually socialist.
One or the other, cannot be both, unless the D party is in fact NOT a genuine political party with rules, platform, and structure.
I never understood how he got to run as a Democrat. His party affiliation is “I” which he reverted to last time he lost.
