Am I misunderstanding this? All the comments from before and after the election, from Ohio and nationally, were about how massively the Obama campaign was outperforming Romney in the efforts to get their voters out - knocking on far more doors and talking to far more people on the phone. Given the election result wasn't a landslide in voter numbers, that suggests to me that the Obama campaign had to work far harder for the votes it got.
Or is that not how you meant that
