I'm a royalist myself I believe that there is merit in haveing a non political head of state and regardless of our political differences we can be united as one country. We have continuity 'the king is dead long live the king ' [or queen].
I am intrigued by our American friends still haveing some interest in our head of state and the royal family.
Is it celebrity status? Do Americans regret not being part of the commonwealth? Are the royals in America just mainly interest for womens magazines.
If there are enough royals over there maybe you should have a referendum to change the constitution. You would then have to learn to play cricket instead of baseball.
