That’s what the Democrat propaganda blitz is about (as recently seen on Drudge). They’re pushing to de-legitimize the President with the delusional hope that they can somehow convince enough Senators to oppose the Kavanaugh confirmation.
Some of the most influential (rich) political constituents want gun control more than anything else, because they don’t trust working class Americans with firearms. They’re afraid that if they do anything despotic and evil enough, that the populace will attack them. And they want control—complete control over people, markets, business, natural resources, etc.
Yes, and they hate the idea that following the Second Amendment shows the Constitution really does limit government power in an obvious and easily tested way.
They also hate the idea of independence, responsibility, and freedom that gun ownership tends to generate, where it is legal.
