"Operating with the baseline assumption that Sanders runs only if Biden doesn’t, another condition is that no serious politician with Sanders’ worldview runs as well. If a credible advocate for democratic socialism and anti-imperialism steps up to the plate, then Sanders should use the occasion to pass the torch to the next generation and act as a surrogate for his chosen candidate. (Sanders’ circle has reportedly encouraged Rep. Ro Khanna of California to consider a presidential bid, toward that very end it seems.) Assuming those conditions are met, another Sanders run wouldn’t excite me the way his first two runs did, but it could still be a force for tremendous good. Sanders has become an extraordinarily influential politician through his previous two runs. In 2020, most of the major Democratic candidates took on some of his signature policy proposals like "Medicare for All" — or positioned themselves by holding them at some kind of measured distance. They did this because they believed that Sanders was tapping into real desires in the progressive Democratic electorate, and because they viewed Sanders as a serious threat whose ideas should be co-opted or moderated instead of ignored."
