Which ceasefire candidate should I vote for?

I know voting by itself cannot bring about change. However the right person in the right position, who is supported by the people, would have a legitimacy that revolutions often lack. The establishment candidates won't even debate, how can they be considered legitimate.

How am I suppose to choose between the three hopefuls I actually like though?

Jill Stein seems like she has the best chance to win, but I don't know if she is revolutionary enough.

Cornel West seems like he might actually be able to kick off a revolution, but I don't know if he could win.

Claudia de la Cruz seems amazing but is still very much a bit of an unknown.

Am I just suppose to roll the dice here? I think I could vote for any of these three with a clear conscience, but my favorite depends so much on the day.
