You can only pardon someone who was convicted of a crime. This was a topic with “general” Flynn, who Trump desperately wanted to prepardon so that they would stop digging into his obvious and blatant corrupt ties to foreign oligarchs.

The worst I’ve seen are campists, but I’d argue they’re right wing because their specific opposition to the left and never to the right. It’s hard to argue that any radicals are leftist when their beliefs abandon humanism from any angle that’s pro-russia or pro-china, or when they criticize AOC for perceived slights while letting the right get away with a trans genocide, for example. To the extent someone is not a humanist is the extent to which they’re not a leftist.
