Here is John McCain, up to 48.5 on InTrade or is that just because of the recent Gallup poll?Here is the Gallup poll he is referring to, and I don't think that is directly the case. I was looking at Intrade this morning after the poll was released and it was still 60/40 Obama, and the media polls have been this close for awhile.
This morning Ohio and Virginia looked much more solidly Obama, but he is trading even there now with McCain. Without looking over every state, they seem to have experienced a good deal of volume and price movement today, which may or may not have to do with the Gallup poll on the broad national average. I think the question is, what has changed people's perceptions about Ohio and Virgina?
Note also that, based on the Intrade electoral map, that Ohio and Virginia are enough to swing the election to McCain.
