I didn't vote in the poll because I figured the OP wanted a UK-only response.
Obviously I'm interested, but I live here.
I think there's a large gap between interest here and apathy... half are apathetic (let's get this over with...) and the other half are overly enthusiastic trump/hillary supporters. I'm probably in the middle, but I get the sense a lot of people are feeling divided on the election.
Strange times.
