This doesn’t explain why she gets more male than female support which was the point being made.
Can you elaborate on your second point though? What policies are you referring to?
As for your first point, I haven't seen the numbers you're describing. I'd need to see where, what states, and the education levels of the men/women, as that would skew the results. Gender is one thing, but without knowing other details about those people, it doesn't tell a full story.
As for the second point, I mean is it even debatable this has been a GOP strategy? It's been well documented in a number of articles and books. The GOP is the party of anti-intellectualism, and has been for quite some time. As for policies to carry out that agenda, off the top of my head it would be their support for religion over science in schools, anti-abortion stances, making government, at all levels, dysfunctional so they can point to government and say, look, big government doesn't work, when it's been nothing more than a self fulfilling prophecy.
On this latter point, The Fifth Risk by Michael Lewis does a good job of describing this.
As for how GOP policy has evolved since the days of Eisenhower through the Kochs and how even they lost the plot with the rise of Trumpism, Democracy in Chains does a good job of describing this "policy" or "strategy"
