Here are people of various political leanings. In many cases, I have only a guess. Many probably supported Sanders, many no doubt voted for Clinton. Several supported Trump. At least two were carrying guns. You may or may not be able to guess which ones are which, although in some cases affiliations are surely clear.
Some of the Trump supporters were there to march for women's rights, not to support Trump. People are complicated.
Look past your guesses and see them as people. They're all people. They worry about the same things, they have the same hopes. They want to be OK.
