Any way you slice it, Obama is leading in states that account for well over 270 electoral votes. As we've said a million times before, Obama needs only Ohio, Florida or Virginia to prevent Romney from reaching 270 electoral votes in most scenarios. Romney needs all three.
Romney maintains a slight lead in aggregations of many polls. HuffPost's Pollster listed six new polls on Monday, and Obama led in only one. Romney led in three of these, and two were are tied. Pollster, which has a very transparent method of aggregation, combines all recent polls and has Romney up 47.4 to 47.2. RealClearPolitics, which aggregates polls with a completely opaque method, has Romney up 47.6 to 46.7.
If you are a poll junkie and you need your latest fix, I suggest following the latest polls in Florida, Virginia, and Ohio. If you are still obsessing over national polls, I suggest you brush up on the Constitution. Just in case, here's a link. It's free.
