They do that by lying and gaslighting their voters. Fox News will call January 6 a "day of peace" and refuse to show the footage from that day of the insurrection, to the point where when Republican voters are shown footage of insurrectionists beating cops with American flags and crushing them in doors, they are surprised that's what actually happened.
That's the degree of information control that's necessary to make Trump sounds presidential, and we shouldn't wish our own representatives to gaslight and lie to us like that.
