As well as the Battleground tracking poll and several non-tracking polls. But I think that the problem here is that Rasmussen's polling for Tuesday was a huge outlier for Obama. That day drops off tomorrow. If you replace Tuesday with the Monday polling that dropped off today (which is more consistent with his usual results), I calculate that Obama's lead would drop to 48-46.
every time i follow a thread about a poll, someone says that Obama's good day will drop off tomorrow... however, it doesn't seem to change anything... i may be wrong, but i have that perspective... McCain is not having any really good polling days...
