I'm optimistic that while it'll still be incredibly different for any woman to achieve the kind of prominence that makes the idea of a presidential run plausible, I do think that female candidates for president will be taken much more seriously in the future by our media. The media likes to quickly write out all marginal players fairly quickly, of course, but the idea won't simply be dismissed and a prominent female senator or governor who attempts a run will be treated as a real candidate.
Baby steps.
