Is that 'Bernie' cannot deliver these things as enacted law, no matter how much he runs his mouth about them, and how virulently he slangs people who do not hail him as leader of the liberal and progressive cause.
Further, on the basis of how 'Bernie' behaved in 2016, there is every reason to believe his continued jihad against the 'Democratic Establishment' will aid the cause of Trump's re-election (one shudders to write the words), as in 2016 it certainly aided the creature's campaign. Many people accordingly see 'Bernie' as a positive menace to liberal and progressive hopes, since continuation of Trump in office and McConnell in control of the Senate will set back progressive hopes for a generation. This moves many to active anger when 'Bernie' runs his mouth about things they desire because they understand that whatever 'Bernie' may say, what 'Bernie' does works against their hopes.
"From Bernies perspective, dropping out of a race once you have no chance of winning is peculiar behavior that can only be explained by the work of a hidden hand. For most politicians, though, it is actually standard operating procedure. Only Sanders seems to think the normal thing to do once voters have made clear they dont want to nominate you is to continue campaigning anyway."
"When things are not called by their right names, what is said cannot make sense. When what is said does not make sense, what is planned cannot succeed. When plans do not succeed, people become uneasy. When people are uneasy, punishments do not fit crimes. When punishments do not fit crimes, people cannot know where to put hand or foot."
