I was going on the media reports of the campaigns' reports of their voter contact - everything I saw seemed to be Romney campaign telling a journalist or tweeting that they'd had X many contacts at a set point and the Obama campaign saying they'd had 3 (or 4) X at the same point. Of course there are always issues as to what two different organisations mean when supposedly reporting on the same thing, and I wasn't actually keeping track of the reports in any scientific way but just noted it seemed a consistent trend.



that makes sense. The Obama campaign might bang on 10,000 doors and the result is they speak to 4,000 Democrats who will vote for Obama as a result of the contact but the Romney campaign might have banged on 8,000 doors and spoken to 5,000 Republicans but only 2,5000 of them would be convinced to vote for Romney with the same level of persuasion as it took the Obama campaign.
