The wonders of a 'nobody'.

The US elections for 2008 seem to consist of idealistic candidates. NOT trying to be stereotype or anything but consider how one candidate is a woman (now comes the possibility for the first US woman president?) while another is an African-American (seriously now, a possibility of a non-white president?)
Sometimes the US propaganda's/agendas appear to be movie material. I wonder, are there hidden agendas (though very often we assume that there's always a hidden motive behind everything) or is this really going to happen.
why does it matter?
(yes,Malaysia will be having an election too which is equally important for a Malaysian individual)
But, the US has always been a solitary power that can affect the interactive patterns within global networks. Who comes into play is always important because it determines whether the US reputation can make a change for once, or will they persist with their unfavourable status?
Will they finally make desirable changes to how the world functions (at least on conventional terms) or will they continue to use their privileged role in different ways?
