I think there are many parallel interestes in the Obama campaign and Tikkun's mission. I believe in the power of networking despite differences in core values and strategies to overcome violence, ecnomic disparities, and global harmony.
I feel your work could gain momentum if you worked with the Obama campaign to further your mutual interests while respecting your differences and singularities.
Obama needs the support of spiritual progressives like yourself to make this a political reality. It worked with Gandhi, King, Heschel, and others...Its bound to work in your movement. Think about it and give Obama a call.
