I wish I would've done one of these last week, so we'd have a clean pre- and post-Paul Ryan trendline. But there wasn't much polling last week, and I generally update only when there are significant changes to the numbers.
Meanwhile, the vast majority of polling this week came from two conservative outfits: Rasmussen and Purple Strategies. Even then, Obama maintains a comfortable lead in the electoral collage tally (332-206). Furthermore, like I've noted week after week after week, the numbers to watch are Romney's—he hits 46 percent in just five of these 13 states despite Rasmussen's best efforts. Obama misses that mark in just one—Missouri—a state I want to pull from this list as out-of-play (like I did Arizona), but the narrow 2.7-point deficit certainly argues otherwise.
I'm hoping for an avalanche of polling next week so we can get a solid pre-convention baseline.
