Overall, women are more likely than men to vote, so it’s a coveted group — but hardly a monolithic bloc. That said, more and more women are supporting Democrats for president, while more and more men are supporting Republicans, resulting in a big gender gap. The size of that gap has varied since it emerged in 1980, but we saw the largest gap yet in 2016. According to the Pew Research Center, the gender gap four years ago was a substantial 13 percentage points — Trump won support from 52 percent of men and just 39 percent of women. That gap was even bigger among white voters: Trump won a hefty 62 percent of white men compared with 47 percent of white women, for a 15-point gender gap.

Depending on the poll you look at, Trump is doing worse among both men and women now compared with 2016, but he has lost more support among women than men, including working-class white women. All told, it’s a safe bet that we’ll see a large gender gap in 2020. And we might see the largest one yet.
