What is it that makes Ted Cruz so very creepy?

David Denby, in the New Yorker: "When Ted Cruz lies, he appears to be praying. His lips narrow, almost disappearing into his face, and his eyebrows shift abruptly, rising like a drawbridge on his forehead into matching acute angles. He attains an appearance of supplication, an earnest desire that men and women need to listen, as God surely listens."
