Dan Balz, Washington Post: “It is easy to get confused in the final week of a presidential campaign, and we are at that point in Campaign 2012. There are conflicting polls in battleground states, unexpected moves by the campaigns into new states, widely varying assessments from the partisans in both parties and persistent spinning by the candidates’ advisers. There are also certain realities about campaigns that offer some anchors, if not real answers, for assessing what is happening now and what may happen Tuesday.”
