What also strikes me (playing "angel's advocate" to myself) is the fact that Christ calls us to live in the precise circumstances we're given -- that, like it or not, I happen to be an American citizen living in 2008.
Suzanne, I'm so glad you raise your thoughts because you are echoing the dismay so many feel, and we have the chance to judge this and see how to live as Christians in the world. I don't mean who precisely to vote for, but how to participate in our civic life while seeking the meaning of all this. I hope you didn't feel scolded. ;) I'm trying to understand for myself, so that I won't take a reductive, unhopeful position about our country's situation.
I have often felt resigned about many things in our country, such as abortion or war. Instead, I see so many speaking out for what they want. It struck me that the stem-cell research debate would not die, despite the insistence on letting science have a free hand for "progress". When these researchers found a new way (adult stem cells), they did want something that would not be offensive to so many. It means that the minority is heard, as long as we don't quit. It has been true of the torture debate, which the public won't let up on. It's true of the desire for respect for life, which continues to be a large factor in this election. We're tempted to give up if we think it's about winning instead of about witnessing. And in the end, the victory is Christ's.
