Two years in the making, the 2008 US presidential election is on our doorstep. By the time the campaign ends, the candidates will have spent more than a billion dollars trying to get the job. All those bucks for a position that earns less than half million dollars a year and lasts only four years!

The post of President of the United States carries immense power to make decisions that affect, for better or worse, people the world over.  And the vice-president - who must be ready to take the reigns at a moment's notice - is almost as powerful.That's why John McCain has chosen a woman the calibre of Sarah Palin as his running mate.
