Much of the coverage of Hillary Clinton’s loss in the presidential race points to the Democrat’s failure to dominate the women’s vote. While Clinton did capture majority of female voters—54%, according to exit polling—she lost some key constituencies, including white women, 53% of whom cast their ballots for Donald Trump.

But perhaps even more telling is the yawning gap between male and female Clinton voters. According to the Associated Press, Clinton’s gender gap—the difference between the number of men who voted for her and the number of women who voted for her—hit 13 percentage points. That’s the single largest such gap since the exit poll surveys began in 1972. Al Gore, another Democrat, was the only other candidate to come close to that divide; his was 12 percentage points when he lost the presidency to George W. Bush in 2000.
