He's pushed healthcare reform, which, for nearly everyone on this website, is a very good thing.
He's working on undoing the deregulation of the banking industry that put us in this bad economic situation.
He's actively promoting bipartisan politics, which is, far and away what this country needs.
He's far from perfect. I don't, at all, approve of his position on gun control, for example, but he's not all that bad.
