Nice idea. But you're going to have to actually read their propaganda to appeal to their "reason". Problem is reason ain't fucking there. Try this Twitter account: @womensmarch. 622K followers. They are still running the male/female divide because it is the biggest demographic. 50-50.
To infiltrate the reasoning you're going to have break them free of their personal allegiances.
Eg: "Out of 300 MILLION Americans the BEST candidates we can get are Trump and Clinton?!? There are better alternatives, like [fill in local candidate here] And this is why it is good for you."
