"I respect the will of the people." In one way, it's really kind of a weak argument for switching sides. Well more people agree with this so I'm gonna support it based on that... I don't like it much. Kinda wish he'd clarified that more, with something like "I saw all this support and I had to stop and just re-evaluate my reasons and position on this matter." He just kinda leaves is open for both positive and negative interpretation.
If you'll remember Tommy Lee Jones' role in Lincoln as Thaddeus Stevens, he has a bit about continually being elected to his position by not giving a damn about what the people want- he is there to lead and to make the decisions for them. Which is certainly true to a great degree. But even he knew that he had to listen a certain amount. There is always that delicate balance between leading and ruling, especially when one is elected based on the desires of the people.
As far as the Alluh Akbar thing, McCain's right. You gotta remember that in a LOT of Muslim countries, the law and religious law are one and the same. Their religion is in every part of their lives. Not just sundays. They stop EVERYTHING throughout the day to pray at the appropriate times, not to mention the food and alcohol prohibitions, fasts, dictates for clothing, etc. It doesn't surprise me that Allu Akbar would be a pretty common victory exclamation. It's almost as innocuous as some football tool kneeling and praying after getting a touchdown. Fox is just so closemindedly ethno-centric hearing them talk makes me cringe.
