The only thing I can think of to explain his reasoning is that he's making an election night prediction based on some sort of trend line.
Says right in the corner of the map "Based on poll analysis as of October 6", as it says in the lower left corner of the map.
Not sure what polls show Obama up in Kentucky. I don't think he's even ahead in New America.
analysis = continuing the current trend on to election day? has to be.
Obama is 3 points further behind in the last Arkansas poll than he was in the one before, so no, that's not it, either.
Not sure how a state can be safe for someone who has trailed by at least 9 points in every poll taken there the entire year, but hey, what do I know.
