Can you give me a link to the post-convention state polls that demonstrate this?
Every electoral total poll that I have seen is backwards looking by a sizable amount depending upon how recent each state's poll is. They tell you how things were not necessarily how thing are. They are not going to measure dramatic short term moves. Give the electoral total type polls another couple of weeks for the latest events to work there way into the results.
Looking at your recent posting history -- are you a sleeper troll?
McCain and Obama were pretty much tied in the EC heading into the conventions. All signs are that McCain improved his standing more than Obambi did.
It will just take a few weeks for the state polls to catch up to that reality.
