One reason is Paul Waldman. How delusional need one be to write these sentences on the heels of Van Jones’s resignation?

The branches of the conservative crazy tree reach much farther into the establishment than anything comparable on the left. There are leftists who think weird things, but they are treated with scorn by Democrats.

Mr. Waldman focuses on anonymous cranks and birther kooks. Van Jones was appointed to a high federal office by the president of the United States of America. Want to see how high the crazy tree goes, or how deep are its roots? Yes, let’s explore that together, shall we? Show me the right-wing militiaman and self-described “rowdy white nationalist” George W. Bush appointed to office.

Don’t worry, I’ll wait.
