People by and large do not want "solid, modern, coherent plans". Both kamala and hillary clinton had those.
People want to be told the strong man will make everything better if you just give up a few rights.
Can the democratic party play that game? Sure. Should they? Maybe? I mean, it would be nice to have someone with an iq over 80 and at least a shred of morality and self-respect somewhere in our elected officials.
Does your post, in specific, say anything meaningful? Not really, you just throw out some vapid complaints and then tell us you hope the world will change.
