For a long time, I thought the Democrats were fighting valiantly but just overwhelmed by the oligarchy and the Republicans. Then I saw that the Democrats keep losing fights they should win and figured they must be just weak and ineffectual. Then I kept seeing them backing off without putting up a fight at all and decided they were gutless cowards. Finally I noticed that enough of them keep voting with the Republicans to always make sure the Republicans more or less win almost every fight, and that they keep starting from a Center position and bargaining to the Right, and eventually after enough of that it became impossible to ignore the only conclusion that actually fits the facts: The Democrats are not over matched, they aren’t weak, they aren’t cowards…they’re complicit.
I can tell you right now, there won't be a legal route to a new constitution without a civil war. There is no way that enough people in power would support rewriting that document.
