The economy is important. So is education, health care, and many other issues... but none of that matters if our very security is at risk. And since the president has much less power over domestic issues, I feel at this time his strength should definately be in foreign policy.
I believe this is the most important election I've ever voted in, and it's mostly based on foriegn policy. 9/11 fundamentally changed my perspectives and priorities. Now more than ever we need a president who can lead in the right direction, not play the political games, and stand firm on principles. The pragmatic, appeasing, whim-of-the-moment foreign policies of the past threaten to cause a great deal more harm to us and the world. That said, I believe in the 'Bush Doctrine' and I think he's basically on the right track.
