He’s technically always been an independent so I don’t know what the big shock is about. They technically shouldn’t have let him run as a Democrat anyway since he was only using it to get on the national stage. He should have been forced to maintain his independent status.
Anyway, the only thing this crazy old shyster is doing is trying to pressure the DNC into giving him the nomination. If he goes independent then he takes an assload of votes with him, thus guaranteeing Trump a reelection.
It’s a smart move and the equivalent of creating a really good bait thread.
