Bernie's foreign policy is absolute trash and Parenti was right to break with him over Bernie's support for the destruction of Yugoslavia.

If Bernie managed to get elected and not get couped in the process, then by some miracle he managed to implement the domestic reforms that he envisioned, it would be social democracy at home and some variation of business as usual on the international level.

Still, I think that Bernie would rely upon popular support and that means that imo he'd be more responsive to his voterbase than "Let's vote him in now and push him left after" Biden would be. But who knows?
