In 2013, Obama received an average of 82 percent approval from Democrats and 11 percent of Republicans — a 71 percentage point gap that rates as the fourth-largest since 1953. It's the fifth year in a row that Obama's polarization rating — the gap between the parties in his approval — has been in the top 10. That's the most of any president.
Obama's 2012 rating was 76 percentage points -- the highest ever calculated by Gallup.
Obama has now surpassed George W. Bush as the most polarizing president in the study. Bush holds four spots in the top 10, including the second and third for 2004 and 2005.
