It is a party issue. The reason Democrats couldn't effectively run on the issue of democracy is that they THEMSELVES did not treat Trump as a threat to democracy. Actions speak louder than words. Democrats called Trump a fascist and a threat to democracy. But they didn't even start an investigation of him til two years into the Biden term. That man should have been arrested day one, hauled in front of a military tribunal, charged with treason, and dealt with accordingly. Any SCOTUS justices that tried to prevent this should have been charged as accessories after the fact and similarly tried as enemies of the republic.

THAT is the rational response to a former president that tried to overthrow the government. Trump should have been six feet under before Biden finished his first 100 days. That is the kind of urgency that is needed when a true existential threat is present. Look what happens when a random citizen tries to walk into the White House carrying a rifle. Do you think they weigh the political calculus of dealing with the person and how to respond to them without angering voters? No, they do what is necessary, then and there. That is what you do in an emergency.

What kind of existential threat do you just ignore for two years and then slow-walk? If China were invading Hawaii, would we move with that kind of sloth? No, an existential threat requires immediate action. By giving so much deference to Trump, Biden made extremely clear that he didn't believe Trump to be an existential threat to democracy. Entirely because of his actions, any later campaign pleas about the threat of Trump fell of deaf ears. If the president of the United States won't take something seriously as a threat to democracy, why would anyone expect voters to?
