The definitive accounting of Barack Obama's legislative accomplishments. It's not a Ted Kennedy-esque list of things, but it shows that Obama's career in the Illinois State Senate and then the US Senate has been brief, but action-packed. I think it stands up perfectly well to Hillary Clinton's record (unless you accept the view that she deserves credit for everything Bill Clinton did that you like, but didn't agree with any of the stuff you don't like) or John McCain's. Remember -- don't go on TV as an Obama surrogate without it!
