The US presidential election of 2000 was one of the closest and most contested in history. It was more than a month before the result was decided after a Supreme Court decision. It all came down to the vote in Florida, a 'swing-state', where irregularities and technical problems added to the confusion. In the end it's thought there were just a few hundred votes in it, but years later, the result, and the handling of the election in the state, divides opinion. Callie Shell was the official photographer for Al Gore's presidential campaign and documented the dramatic events behind closed doors in pictures. She's been telling Rebecca Kesby what it was like to be there.
