Did the US Media 'gaslight' the American electorate?

TO 'Gaslight '  

IS TO  manipulate (someone) by psychological means into doubting their own REASONING, DECISION MAKING  AND IN SOME CASES SANITY.

Gaslighting is a form of psychological manipulation in which a person or a group covertly sows seeds of doubt in a targeted individual or group, making them question their own memory, perception, or judgment, often evoking in them cognitive dissonance and other changes, including low self-esteem, thereby rendering the victim additionally dependent on the gaslighter for emotional support and validation. Using denial, misdirection, contradiction, and misinformation, gaslighting involves attempts to destabilize the victim and delegitimize the victim's beliefs.
