I'm glad I'm seeing pushback by @mekkaokereke against the "women hiding their votes from their husbands" meme. I'm sure it exists, but it's not a big factor, and in exit polls in the US, married women vote almost the same as married men - the gender gap is about younger and unmarried voters, whereas a large majority of women married to Republican men are Republican themselves. Go to https://edition.cnn.com/election/2020/exit-polls/president/national-results and scroll down to gender by marital status.
