Self-proclaimed Center Left bias
Damon clearly expresses his bias (we applaud such transparency), considering himself "center left" in this opinion piece), and his stances on various issues (some described in "I'm not a Democrat. I'm an anti-Republican") is consistent with his self-rating as left of center.
He is a senor correspondent at The Week (rated Lean Left).
