I am not in the practice of discussing my votes...but since I am a Canadian citizen and cannot vote here, I suppose it would be ok if I gave a sneak preview into my political sways. A friend asked me to explain if it was so that I would have voted for Obama - why? This is what I answered...(*note* this is not representative of my entire thought process or reasoning. I only approached two hot topics superficially...foreign policy and healthcare reform.)

Obama: Yes, I would have voted for him. Just like in any election, you vote for the better person, not because they represent me in every way, shape or form. He is smart - and it has been awhile since a really intelligent person was in office.
He is eloquent, inspiring and stands for good values. ie. wanting 1,000,000 people volunteering in the PeaceCorps and Americorps. These things encourage us to look outside ourselves and help others. He encouraged school children to work hard and
succeed inspite of their surrounding circumstances. I think our generation is extraordinarily selfish and we value ourselves by "things" and "possessions". No one ever gets married and slowly upsizes their houses and cars, for instance. Everyone bought houses that were the size, or larger, than their parents'. Our work ethic is down and we are becoming disconnected as human beings - internet, texting etc. So little changes like that, I think he was inspiring.
Policies? - Healthcare MUST change. I have had a very unique view of it actually being in the field. There is billions of dollars of waste in the current system - one of the main criticisms of any govt involvement - in the privatized system...the difference? The cost of waste gets passed to the consumer (hence the premium increase of well over inflation over the last several years) so it isn't recognized as waste. At the end of the day, there is going to be give and take in all systems - including a new one. But is the positive more than a perceived negative? I say yes. Criticism of Obama (because i think every rational person should see the weaknesses of their position or person they support) he is OVERLY bipartisan. He is feeling the pressure of a minority of people and bending his plans TOO much. This could be a problem because by the time a healthcare bill comes through, it will be so watered down and may lose its "change" goals.
Foreign policy - I too am a pacifist. Of course I believe we need a military, and they do great things. But I am NEVER in favour of a preemptive strike (Iraq); I am always in favour of acting with the world's players, not unilaterally; I am in favour of coming to the table and talking to some of our worst enemies. I could never understand Bush policy and subsequently McCain policy that they wouldn't even talk to Iran (Ahmedinejad). How can talking to someone insinuate that you believe in their policies? In fact, it gives us, the USA, a chance to sit in a civil setting and discuss our demands and expectations. It is better than public talk AT each other which solves nothing - it only increases misrepresentation and tensions. He has done a lot for the world...one reason I began to support him over Hilary was because she had become toO militaristic in her statements, like McCain. That had not worked for us the last 8 years and in fact has only engendered further distaste for the US and its policies. Diplomacy, in my view, should always be exhausted first. Nothing is solved by war - sometimes necessary - but it never ends well.
