Context:
Ruben Studdard emerged as the winner, beating Clay Aiken by a small margin. Out of a total of 24 million votes, Studdard finished just 134,000 votes ahead of Aiken.

In an interview prior to season five, executive producer Nigel Lythgoe indicated that Aiken had led the fan voting from the wildcard week onward until the finale.
