Yeah I get that the purpose of that Illinois election law was anti-Communist political posturing, but even if we can't bar him for being affiliated with a group intent on overthrowing the government, it should lend credence to him being an insurrectionist in the other cases currently in the courts or for new challenges in states, as applicable.
More like Hitler I think. Mussolini offered to crush ongoing communist and anarchist revolts to secure order for the ruling elite and they were happy to give him the power. Hitler got into office democratically by leveraging an economic crisis and then used loopholes and violence to secure a role as dictator.
