She is absolutely correct to say that the counter to Trump’s “strongman politics” is a deeply righteous and moral campaign. The Democrats either don't understand this, or they think that brute-force browbeating can replace it.
Democrats have, for too long, spoken from a position of moral authority when they have no real basis for it.
A righteous and moral campaign would seek to increase diplomacy and stop the US-backed wars in Ukraine and Palestine. It would fight for free healthcare and cancellation of student debt. It would crack down on corporate exploitation and police brutality. All of these things are possible within the confines of liberal politics.
