The different polls may disagree on how much of a lead the Democrats have, but there is one thing they all agree on -- that there is a huge gender gap in this election. While men prefer Republicans in many polls by a small margin, women prefer Democrats by a much larger margin.
That would not be good for Republicans if men and women voted in equal numbers. But it is worse for them than that. Women have voted in larger numbers than men for quite a few elections now.
