Unfortunately for the Republican party most women that once identified themselves as belonging to the Republican party have left and became independents who will be voting for Hillary. The young people that are coming of voting age don't see themselves aligning with their old senile bigot and racist grandfather's way of thinking either so my guess is the largest majority of voters voting for Clinton will be all those under the age of 65. Where women once followed their husbands to the polls and voted as their husbands are all but over. You can bet many women with Republican husbands will be voting for Clinton just so that they can be part of a large number of growing population that actually want to see a woman in the White House during their lifetime.
What would it take you ask? My unsolicited diagnoses would be a complete mental workup along with some antipsychotic medication and a recommendation that he be placed in an alcohol abuse program for the elderly.
