He believed in 2 things which might help you. I don't really know what term you are looking for, but here are the two things he brought to the table.
1. He was very concerned about states rights believing that the states should have the balance of power shifted to them.
2. He believed that domestic policy had to be addressed rather than war and terrorism which is what Bush emphasized.
He was accused of being more of a socialist than a federalist (which might even be true). You could call him a social democrat.
