Analogy fails. Gingrich is like Ayn Rand but he’s less meretricious and more the braggart. He’s Bull Connor but with more social Darwinist claptrap. He’s Updike’s Satan in “The Witches of Eastwick” but less sexy.
He’s the puff pigeon of right wing intolerance. In this way he’s like the canary in a coal mine, revealing toxicity. But of course he’s less interesting to watch.
