I should clarify: The news feature is separate from the profile. So, whilst I could certainly write about many of the things you've all mentioned above in the news feature, the profile is a (short) story based mainly off of an interview with a (hopefully) interesting person. A Republican intending to vote for Donald Trump in a left-leaning city like London with a media and citizenship that is almost uniformly anti-Trump is an interesting figure and, I believe, would make for an interesting profile piece.
But as I've said, I am willing to open things up but as yet I am finding it hard to find anyone willing to talk with me. I understand it's a time commitment and, really, the subject isn't getting anything out of it other than the remote possibility that the piece may be published (and many people have told me any sort of publication would make them less likely to talk to me.)
I have a little time. The election is of course next week, so if I could speak with someone within a few days of the result, great. If not, well, I have one or two backup ideas but it would be a shame, for me at least.
