I think the last sentence sums up the British attitude towards names compared to others:
"The Americans say that any American child has the right to grow up and be President. So, who knows, with a few more common sense rules in the adoption system, little Chardonnay might one day grow up to be Prime Minister. Sadly, as things stand, it?s highly unlikely"
And I doubt that Condoleezza Rice would have been as succesful in the UK as the US...
