The Presidency is odd because you don't have all the hassle a Prime Minister has in working your way up through a party structure. I prefer our system as no PM can get to that position without getting selected by a local party or the party establishment to become an MP (decent chance of a nutter getting though), getting selected by the Parliamentary Party (low chance of a nutter getting though) and getting selected by the membership to lead the party (extremely high chance of a nutter).

If you have the money you can railroad the party establishment a lot easier in the United States although it's still hard. Trump is a rare exception. Obama wasn't the establishment choice at first but he wasn't unpopular with the DNC either.
