Obama's title as most liberal senator:
He is #1 while Hillary is #16. Out of 267 votes, they differed on 10. Joe Biden was #3. This list is as accurate as the U.S. News & World Report's college list. See the following blog on why the National Journal's stats are misleading:

"Of the 65 votes included in the study that both senators were present for, they only differed twice — on a measure that sought to establish an Office of Public Integrity to handle ethics complaints (Clinton voted no, Obama yes), and on a measure that sought to allow certain immigrants to stay in the united states while renewing their visas (again, Clinton voted no and Obama yes)."
