If a third party gets 15%, they get a third podium on that stage, which I think would be worthwhile and healthy for American democracy especially in the face of the two most hated candidates in history.
I don't particularly care if it's Johnson or Stein but I'd like it to be someone. Ideally we'd have both. Johnson is pretty close to breaking 15% in a lot of polls.
Of course this line of reasoning simply suggests that pre-debates, if anyone asks you should /claim/ to be voting Johnson (or Stein), not anything about where you should actually vote.
Not to mention the CPD would almost certainly change the debate qualifiers immediately to still keep Johnson out, same as the DNC did with Lawrence Lessig.
