I haven't even ascertained how there is any evidence of an existence of a "silent majority." I know Trump thinks he can channel 1970 Richard Nixon, but he ain't bringing back 1970 demographics.
Actually, all the 1970 vibe I am getting is from the Left, burning towns, protesting, KMA politics, and communism wrapped in race and topped with "FU whitey".
SSDD.
It angered a significant portion of America then, and, at least in these parts, still does.
My neighbor still flies his Trump 2020 flag with impunity, right under Old Glory...
