I'm having flashbacks to when I was in high school in the 1970's while Nixon was at the height of his powers.

The difference is Nixon had real domestic enemies to worry about: The Weather Underground were bombing buildings, heiress Patty Hearst was kidnapped by the "Symbionese Liberation Army", the Black Panthers were making demands which conservative America found frightening, mass protests were going on about the war in Vietnam on college campuses which resulted in the deaths at Kent State. Nixon believed these protests were driven by Chinese and Soviet influence to support North Vietnam in the war. The CIA’s Operation CHAOS spent years looking for foreign control of the antiwar movement and reported back that there wasn’t any.

What domestic enemies does Trump have? Antifa is a philosophy, not an organization. Black Lives Matter protests were his last administration. There have been a few lone wolf attacks like the Dallas ICE sniper, but the domestic threat is no here near what Nixon faced.

Under the Trump's White House directive NSPM-7, which defines a potential domestic terrorist as anyone expressing “anti-Christian, anti-capitalist, or anti-American” views, DHS launched an operation to find a “network of conspirators” against ICE.

The surveillance op in the Wired article targeted labor unions, a climate change group and socialist collectives — the SEIU had three years of wire transfers investigated, and the AFL-CIO, DSA and Showing Up for Racial Justice were also investigated. That’s the mismatch: a 1970s-scale dragnet for a threat that isn’t 1970s-scale.

Trump appears to be grabbing power for the sake of grabbing power.
