It's all a question of emphasis really. As Dave said, the Dems now control the Congress; different issues will come to prominance.
I do agree with the sentiments regarding 'mixing' two opposing views to get centrism. Being economically classic liberal/right and socially classic liberal/left, I don't think I could consider myself centrist. My social views are the most inbuilt as they are based on what I'd like to consider to be coviction and life experience. I can be swayed by rational economic arguments however.
In countries where social liberalism has effectively 'won' then I sit right of centre pushing for increased or maintained social liberalism. In the USA, there is still a long way to go to reach European levels of social liberalism; the fight is still being fought particularly on gay rights and attitudes. There I support the Democrats pushing for increased or maintained centre right solutions to economic policy
Social policy is
always my top priority; that goes for protecting the rights of individuals and their personal freedoms from an intrusive state or religious influence too.
If I have time, i'll do the tally: see how it adds up.
