Despite Mike Huckabee and Mitt Romney winning several primaries and caucuses last night, John McCain has all but clinched the Republican nomination.
McCain adviser Charlie Black said, "To date, we have 775 delegates, Romney has 284, Huckabee has 205. It takes 1,191 to clinch the nomination. There are 963 left to be chosen, so Romney or Huckabee would have to have all of them -- all of them -- to get to 1,191. Now you can't do that because a majority of those 963 are chosen in proportional primaries, which means you'd have to get 100% if the vote to get them all."
