Can Brits be trusted to elect their own head of state?

No. Like most elections it's a popularity contest. Boris is the crazy buffoon with the white I've just got out of bed hair, and affected accent. He knows what he's doing in distracting his audience from his ineffectiveness. People like Theresa May lack the charisma, but I've more respect for her since she was ousted in statements she's made. Or did you the monarchy, who I see as having no power and are just there for the tourists?

NO.   That is why our head of state is hereditary.  On those occasions when it has been necessary to change the succession, that has been done by parliament.

Of course we could but most people don't want to do in Britain as Her Majesty has taken on that role over 60 years far better than any Tony Blair or David Cameron ever could. God save the Queen.

Yes we can, but we are so fortunate to have a head of state with so much dignity and grace as Her Majesty the Queen, who was given to us by God himself.

Our head of state is HM Queen Elizabeth. We don't elect royalty. It works with family succession. Dopey Charlie is next in line.
