They appear to be human life forms. The men wear dark suits, white shirts and ties; the women, fashionably correct apparel. But if you linger at the sight, it turns out these are illusions. They are bloody anarchists, hard right Republicans who don't like anybody, or anything, that doesn't entirely agree with their passionate goals of shutting down an evil government that pays their wages of sin.
The TV scenes reporting Kevin McCarthy's withdrawal as the possible successor as speaker revealed a virtual Republican Party on a clanking merry-go-round with headless horsemen. These are dangerous creatures. Even more so, however, because they are morons isolated from reality.
As the party shatters, the calliope is deafening.
