Tuesday featured comment
"YouGov did follow up (literally repolled the previous set of likely voters) polls on its previous set in most of the states and found Obama in the lead in all the swing states except NC, albeit by only 1 in VA and FL. This is in line with its national polling putting Obama three points up. It also suggests the possibility that much of Romney's gain has been due to response rate changes, as RAND also shows considerably better numbers for Obama than most other polls as well. That doesn't make them right of course, it just makes them different to the phone poll results, and whether or not that makes them more or less accurate is something of an unknown at this time." - cwpiper
