I'm voting for Hillary.
Black men could vote (1870) 50 years before women could (1920), so there is no denying that racism has been in public policy longer than sexism/male supremacy. In that, maybe it's evident that racism has also been in the public eye longer. For nowadays, racism is recognized more easily the moment it happens, and more people check themselves to see if they're being racist.
Sexism/male supremacy is still in most cultures, and most people, even women, are unaware of it. Think how many mainstream movies have even one conversation between two women in them.
Most democrat black women will vote for Obama. All democrat white men will vote for Obama. They are willing to put their remaining racism aside to vote for him, because there is no way most of them would even consider ever voting for a woman. Woman president? Not an option. No matter, the republican will probably win.
So I'm voting in spite of no woman ever becoming president of America. When one group is in power, it does everything 'in its power' to keep it that way, even if another group would be better at it. Therefore, white men will always be in power in this country, even though women would do a better job of it.
Meanwhile I guess the only method (not really tried yet) to put sexism/male supremacy in the public eye on a mass scale is to point it out, EVERY TIME, the moment it happens, like people of color have done with racism. So ladies, ready to shout out a lot of "WHAT did you just say?!"'s?
