> When's the last time you saw a Trump supporter on this site?

Today, several. They made themselves known in several threads related to recent events.

It's against the guidelines to call out posts/posters, but you can use the HN Algolia to list the most popular threads from this week/month and you'll see plenty of them.

Which guideline? https://news.ycombinator.com/newsguidelines.html

I think it should be fine for you to link a few "I support Trump" comments from the past week? Note that believing the Trump administration is correct on a particular issue, or that they are being unfairly criticized, is not the same as advocating that people vote for Trump. I wasn't able to find anything I would consider actual Trump support from a quick skim of recent threads. I don't believe I've ever seen it on HN.

Or perhaps people can support deportation of illegal immigrants without being a "Trump supporter".
