JOE SESTAK.
Military. Moderate. And anti-establishment.
Did I inspire this a few days ago?
I think you're absolutely right for the record, but I think other options are also possible - John Allen had a great convention speech and has progressive credibility as president of the Brookings Institution, Bill McRaven has an incredible record (who can attack a Navy SEAL who took down Bin Laden?) and has made public statements against Trump's attacks on the media immediately after his inauguration. Seth Moulton also applies - very anti-establishment internal to the Democratic party with a stellar war record.
