For John, BLUF: The "Unenrolled" still have time to file papers for a Senate run. Nothing to see here; just move along.
Good news for John McDonough, John MacDonald and others of their ilk—they can still file nomination papers to run for the US Senate Seat of Mo Cowan, which used to be the US Senate Seat of John F Kerry, now our Secretary of State.
For Non-Party Candidates, 3 April 2013, at 5:00 PM is the last day and hour for submitting nomination papers to local Registrars of Voters or Election Commissioners for the certification of signatures.
Now is the time for you independents to show that you are the "Majority" in the Commonwealth and to put up hour own candidate for US Senate—or candidates.
Go for it!
