Editor’s note: our in-house legal counsel has informed us that imitating someone’s signature, even for the purpose of valuable satire or obvious comedy, is illegal, constitutes forgery and could result in criminal charges. Thanks, but it’s a little late to be telling us that now, right? For what it’s worth, John McCain is a straight-shooting, hard-working legislator and he didn’t write this letter. Do you really think he writes his own letters, anyway?
