Hillary Clinton will, eventually, make her entire campaign about her gender rather than her merits. She has to, after all, since her only merit is basically her gender (at least as far as the #waronwomen voters are concerned). I mean, did you expect her to run on her foreign policy record? Her political experience? Her winning personality?
She no longer seems to be struggling with opposition in her own party, since Bernie Sanders appears to have reached critical mass (there are only so many people who are fine with socialism, and those people usually have their college final exams right about this time), and Martin O'Malley has no significant presence to speak of, so Hillary Clinton is now happy to lay the groundwork against her forthcoming Republican opponent who will, likely as not, be a man. And according to her latest campaign ad, 44 men in office is more than enough.
