The charts above are from the Pew Research Center.
While men are fairly split between Biden and Trump, women are not. Trump is in serious trouble with women -- every poll shows that.
And that's good news for Democrats, because as the top chart shows, women make up a larger segment of the voting population (about 4% more than men). This difference holds true among Whites (3 point), Blacks (10 points), and Hispanics (5 points). Only Asians are different, with men having a 1 point advantage.
Women also hold the advantage among all education levels.
With political party identification, Men have an 8 point advantage in the Republican Party, while women have an 18 point advantage in the Democratic Party.
