"CHANGE WE CAN BELIEVE IN.... STAND FOR CHANGE" .....
Amongst the current crop of front-running candidates, who is going to represent and support "change"? Obama talks part of the talk, and makes it appear on the surface as if he is for the people...(he's damned good at it, he is an excellent orator). However, if he prevails in November, he will not walk any of the walk (let alone half of it). He's 2 moves in front of the rest of us, and the muscle that will be assembled in an Obama White House are 5 moves in front of him.
There will be no change, apart from the spokesperson in the form of the CEO. It will remain business as usual. Another 4 years of the current "in pur faces" approach could result in civil unrest, and the most effective way of defusing that potential is to get behind a charismatic intelligent person with communication skills (albeit insincere ones), i.e. someone who can string a sentence together, to present a fresh, more velvet gloved approach to towards whatever kind of society that the powers-that-be would like to realize, or impose upon us.
Having said this about Obama... Clinton would be several degrees worse. I also believe that the majority of America isn't ready for a black person of any gender, or a woman of any race (sadly).
Hence my prediction that McCain will win in November, by fair means or foul.
