I used to work with someone many years ago who was actually probably just about the nicest person I worked with in that job, just a genuinely straightforward, pleasant person.
I didn't keep in touch with them after moving jobs, so you can imagine my shock one day when I saw that they were a Tory MP and indeed subsequently became a Minister.
Utterly bizarre, as I would never have put them down as being a Tory or even particularly political, maybe some of them just hide it better than others!
