It is as Akenaton says. They say and do anything which they (and their handlers) think will win them the election. It's a game. (kind of like a football game) Truth has nothing to do with it. Morality has nothing to do with it. The Big Corporate League that runs the game and owns the stadium wins no matter which football team wins the game. The public pays for the game. At the conclusion of the game one team officially loses, one team officially wins. The public actually loses. The public is eternally divided against each other through being divided into fans of team A versus fans of team B, and they are openly encouraged to despise one another. This renders them powerless and keeps them suitably mesmerized and distracted as the Big League rules over them all...unseen, unthought of, unspoken of, and totally in control of the process.

2 years later there's a semi-playoff between teams A and B for the Congress. 4 years later the whole stupid process repeats itself as the next Big Playoff game occurs for the presidency.

Any truly alternative voices (such as Dennis Kucinich, Ron Paul, the Green Party, and other small parties) are effectively shut out of the process merely by the fact that the Big Corporate League controls most of the voices in the media, and the media focuses its attention almost exclusively on the 2 big offical teams A & B, whom I call collectively the Redemocrapublicants....because they are simply 2 halves of a single entity.

Is one half preferable to the other? At times, yes. To some extent. But make no mistake, they are more of the same you have seen before, and the chances of either one of them being anything more than a compliant servant of the Big Corporate League that stands behind them are practically nil.

Reality being what it is....either team A or team B will win this election. There is no other feasible possibility. That being the case, I would vote for Obama if I had the choice, because I like what I see in him far better than I like what I see in McCain. But, gee, I wish I could see the complete end of both the Democrats and the Republicans forever and the beginnings of a real democracy in the USA instead of the old phony pretence of a democracy.
