Here's a good piece by Fareed Zakaria in Obama's foreign policy.
Zakaria makes the point that Obama is not really at all like his Republican and Conservative detractors assume.
Instead, Obama is actually a realist when it comes to foreign policy....more like George H. Bush. McCain is really the one out in left field.
I suppose this piece points to the real issue when dealing with presidential politics: You can either stick your head in the sand and believe what your chosen party tells you about the opponent OR you can look at the facts.
Unfortunately, many people make up their minds without any intrusion of facts.
I, for one, think it incumbent upon each of us as a citizen to explore and evaluate the candidates critically. That's probably too much to ask of the electorate, viz., that they use their brains instead of their ideologies.
