That link didn't work for me ... basically, here in the US, what matters is not the overall vote total for each candidate, but the Electoral College total.
When a candidate wins any one of the 50 states, they get a certain number of Electoral Votes. The more people in a state, the more electoral votes. So, it's more important for them to win big California with 55 electoral votes, more so than more sparsely-populated Oregon, with 7 electoral votes.
When a candidate gets more than half the electoral votes to be gotten (each state has as many votes as they have senators and representatives in congress), that person wins that particular state.
In 2000, either Al Gore or George W. Bush would have won, depending on who won Florida. The Florida vote as practically a tie, and the Electoral Vote was that close. We won't go into that whole ugly story here, but that's basically how the system works. Usually, the Electoral College shows a definite majority even in close elections, however.
If you're curious to watch the results, they start coming in around 7pm Eastern time (which I think is midnight in the UK).
