I've been looking through Trump's favorability polling, and you will be shocked to learn that his support remains divided by gender, race, and age. The first divide remains the weakest: only a slim majority of women (50.9%) disapprove of Trump, and while he can't win majority support from men, he does have a plurality of them (at 48.3%). Race, on the other hand, remains the strongest divide: people of color give Trumpo his strongest disapproval ratings (63%), while his strongest approvals come from white people (53.2%). Similarly, the age gap is pretty distinct:
Trump is winning most of his support from the olds, with a slight bump from doofuses in Generation X; meanwhile, the only age group where he faces majority disapproval is Millennials (at 55%).
While the sample sizes are too small to specify the intersectional percentages with much confidence, it seems generally clear that race is playing the largest role in determining opposition to Trump, followed by age, and then gender. If you are a person of color, you are almost certainly going to view him unfavorably whether you are young or old; if you are white, then the age trends become more significant. Gender predicts a slight preference, but the other factors seem more important - if you are young you're likely to disapprove of Trump even if you're a man, and if you're old you're likely to approve of him even if you're a woman, and if you're a person of color you'll disapprove either way.
None of this will come as much of a surprise to anyone who's been paying attention to the demographics of American politics in recent history, but the age dynamic is worth emphasizing since it's so persistently ignored by in the media. And for reasons I've noted repeatedly, age gaps are always worth bearing in mind whenever the confrontations and rhetoric between the left and the right start getting militant.
