Furthermore there's an argument to be made that the UK system of government is considerably more modern that that of the US. After all, their system is essentially a direct copy of the UK system of the time, with a few minor tweaks. The house is parliament, the Senate is the House of Lords, and the President is an elected King George V. Signing laws is Royal Assent, dissolving the House is Prorogation, he can even pardon criminals. I say George V specifically because the powers of the crown have been massively reformed since, really from Queen Anne onwards, but the US system has remained frozen in time.
