The answer is yes to your question. I don't want to reveal my professional experience as I'm easily identifiable but have campaigned locally for planning matters and transport issues in my spare time. Rubbed shoulders with academics, think tanks, pan London campaigners, journalists, local politicians, etc. Been inside Number 10, knew a couple of people who campaigned for a seat in the general election. I don't affiliate myself to any political parties as they all have some flaws one or another.
In my experience, especially true in real life, it's generally the person who knows the least that can be the most difficult to deal with.
