I am not sure?
But the map give AR to republicans, even in Clinton-McCain matchup. That's because the last poll done (quite a while ago) is also the only one in which Clinton doesn't have the lead.
I think the maps come from a certain site. If I could remember it, I shall give a link.
You shouldn't have to remember it. You should be able to click on the state and get information about what poll was used, when it was taken, etc.
