In answer to your question, if you count Supreme Court Justice Steven Breyer as a political figure, then you missed him. His wife is from Great Britain.
I was in the right ballpark - I knew it had something to do with spouses, but I put that their spouses are all taller than them. I blame Kucinich. That's an image that lingers.
Bradley and Breyer are great suggestions. These would be much easier to write if I could crowdsource them BEFORE the quiz got mailed out, instead of after.
Occasionally people send them in to one of the email addresses on the site (see the Contact page). When I get really desperate, a few have even been used (with credit).
