My impression is that the current-day Dem's are, in "actions speak louder than words" terms, simply not all that interested in winning elections. Stuff like not bothering to do even the most basic of opposition research on George Santos ( https://en.wikipedia.org/wiki/George_Santos ). Not carefully checking that Biden's marbles were all still there 12+ months before the election. Their slow and half-hearted (at best) response to the RealPage ( https://en.wikipedia.org/wiki/RealPage ) rent-jacking scandal. Etc., etc.
