Sadly, it's easier to vote for the same party again and again, rather than really study the issues, then pick your candidate...
I butt heads with many Americans on a BMW Forum I camp out at, and so many of them are 100% behind attacking Iraq; without ANY remorse! Most of those want Iran to fall next because they are increasing their development of the BOMB...
Here is a quote of my post on that forum...
Hey, here's a thought from a Canadian; you know, we live north of the border...
Consider staying out of other countries militarily; stop killing their civilians, their mothers, their fathers, and their children, stop destroying their economies, stop imposing US Political values and belief systems on others, stop bringing other countries into your Wars, stop hiding behind UN Imposed Rulings, stop bullying others to be like you, and maybe, just maybe these besieged nations and religions may not want to kill you and stop sending terrorists against you!
As well, Iran has had Soviet help in their Nuclear Weapons Program! Just because they are enriching Uranium now does not mean they do not already have Nukes!
I trust even you understand the importance of not pissing off a Nuclear Power...
The justifications used by the average American for the carnage and destruction scares the shit out of me... 
Chuck Shumer: "The amazing thing is when people said they think the country is moving in the wrong direction, they think the war in Iraq is wrong, and the economy is bad and we still lost?" (democratic senator for New York)
John Stewart: "It really seems to me that none of that trumped the idea of dudes kissing."
We must try to make what humor we can of an otherwise dire and overwhelmingly depressing situation.
