While it appears there is a wave of new polling coming out of some battleground states (Ohio and Virginia, for example), there is little news from Missouri.
All we can currently go on were polls that showed a steady lead for McCain
(48% to 44%) right into the beginning of August. If the convention bounce that is showing up in national polls trickles down to us (as it is likely to do) then it is hard to see that gap narrowing at all.
I have to again say that if anyone is seeking in-depth, insightful coverage of political polling-from the latest results to what it means-Pollster.com is the place to go. I say this mostly because I lean on them for a great deal of coverage. They maintain an up-to-date list of the latest polls, run aggregate numbers and analyze what's going on behind the numbers. It's like having your own private pollster.
