I remember when we ignored Europe and we were totally committed to the Commonwealth and the former Empire, and thought imperial preference was the only thing which enabled us to survive, that was a mistake, and it's a similar mistake to feel Britain can't be a hugely successfully country - economically and in any other way - outside the E.U.

Having a Congress with a more diverse educational and professional background would serve the country well. And given the budget challenges facing America today, we might benefit from a few more cold, calculating problem solvers, and fewer courtroom impresarios.
