Good question. From talking to people out and about I am convinced Hillary has a worse problem with male voters than Trump does with women.
Trump has a 10% or so disadvantage with women at present, but Hillary has over 20% disadvantage with men, which I expect to grow. It’s not out of the realm of impossibility Trump could get a 65-35% margin with men overall (and if you remove non-White males, perhaps even higher than that).
