Run, Stephen, Run!
Ben, it IS you! Via RedDan, here's some more information regarding the quest for "Augustine," Ben Domenech's suspected screenname at Red State. From Hotline:

Later that p.m., a RedState post titled "We Need John Shadegg" was posted by "The Directors" -- Krempasky, Ben "Augustine" Domenech, Erick Erickson and Clayton Wagar -- urging in bright red oversized letters: "Call (202) 224-3121 and urge your congressman to support John Shadegg for Majority Leader. This matters."

So the National Journal's Hotline says that Ben Domenech is, in fact, the poster Augustine. Your mission, should you choose to accept it, is to find the choicest Augustine post and ask the Washington Post why they employ someone who referred to the recently deceased Coretta Scott King as a "communist" and how this adds to the substantive debate. They're already getting an earful on the post.blog--seems that people aren't taking to Ben's lyrical stylings.

Update: Even more evidence that Ben is Augustine. Thanks to Amanda from ThinkProgress for the info.
