TTV - I tend to agree that our Royals are more cost effective and a better deal than some presidents although of course in many countries (not France or the USA) the Pres. is a figure head not an active politician
But England is a funny place - we can go for years, even centuries, plodding along with strange traditions, laws, customs etc and then they change overnight - and 6 months later people can't even remember the old system
I doubt Republicans will do it - it's more likely someone royal doing something so idiotic that people suddenly decide on a change......
and the next incumbent looks like a possible I think..............
