I've said it before, but to me the left in this country is ripe for a hostile takeover from the extreme far left. As the extreme far right becomes more emboldened so will the extreme far left.
Sure, people love to tell us that communism is dead and buried, but people tend to gravitate away from things they despise despite known dangers and historical data.
It's not something that will occur overnight, but given the populist platform we might just see the resurrection of far left ideology in ways nobody expects as the alternative to the asshats currently occupying Washington. Workers paradise anyone?
