Sanders is one of the most popular politicians in the US, and his political analysis and messaging remain as relevant and compelling as ever. But while his Tour to Fight Oligarchy is inspiring and important, the broad left badly needs a political vision that goes beyond Sanders.
Okay full discloser I am not American and very much not familiar with prominent figures in progressive American politics other than the Squad, so I have no idea. However, it’d likely have to be the leadership of a coalition of progressive groups and third parties uniting for a more equitable and just society and against fascism, in which case they can just elect whoever. I also think the best/only path forward is a broad progressive coalition founding a third party and both competing for elections and resisting in the streets at the same time, so the leadership would naturally emerge from that third party. The leftist activist base whose only direct interaction with politics until now has been to endorse candidates and vote needs to contest and win elections. Unite the left on that basis and you’ve won half the battle.
