My bad if I forgot to adjust, your map looks accurate enough
His map is absolutely worst case for Obama. Also with the crop of candidates the GOP has, I don't think they have a shot in hell at Jefferson, Araphoe or Adams.
I'd say there's more of a shot for GOP winning Jefferson country than Adams or Arapahoe. Besides, anything can happen if Obama get worse approval ratings than current.
Jefferson does seem to be becoming more Republican than Arapahoe but that makes sense since Arapahoe has more minorities and is slightly less wealthy. Adams also has a lot of Hispanics IIRC and seems to be becoming more Democratic. I don't think a Republican can carry it unless they are winning by at least 6-7% nationwide.
