Don't listen to JoanK and Mergle.
Try to find War instead as the horsemen are perfectly fine with lynching Classical Hero (you can't even be sure there is a fifth Nazi). Even if he is nazi, one nazi and one horseman are much better than two horsemen. In fact, the game is over if you lynch anyone else than War.

I agree the horsemen want to lynch the nazi - it increases their win chance as otherwise there's a risk for them that the nazi would nightkill them and then combine with the town to lynch the other. In fact, to have any shot at winning, the nazi would have to nightkill one of them (but might pick the wrong target).
It all depends on whether Zack is a horseman.
If he isn't, and we lynch classical the last nazi, then after the night it'll be 1 townie, Zack, and 2 horsemen, and I agree the town loses.
If Zack is a horseman, though, we end up with 2 townies, 1 horseman, and Zack, and win, provided we lynch the horseman, as Zack would prob abstain (see my post above).
So lynching classical is a winning strat in that situation. Also, Bhuddafish is probably then War (note how he votes classical while Verarde doesn't). [By the way, JHT vouched for Mayor. Unless he's also horsemen, which is possible, but a dangerous strat as it could have doomed them, Mayor isn't horseman].
If we could be sure who war is, lynching him gives 3 town, 1 nazi, 1 horseman, and we might be in with a shot if Death isn't killing, or the mafias kill each other. But if we mislynch and hit a townie with the lynch today, it's over unless the mafia kill each other tonight.
So although its risky, and there's no guarantee, I think going with CH is our last, best chance. If I've guessed the set-up right, that should give the town its best shot.
But lets face it, the town should have been out of this some time ago. Anything we try now is only a last, desparate throw of the dice.
