51/49 Romney
Romney takes the swing counties, Arapahoe and Jefferson. Obama takes Larimer county.
Seems entirely reasonable. Though I'm curious why you think Arapahoe would flip before Larimer in a 51-49-ish Romney statewide win? That'd require Romney to improve on McCain's vote in Arapahoe at least 2 points more (from a
13 point deficit in 2008) than he improves in Larimer. You know a lot more about CO politics than I and your map is decidedly non-hackish, so I'm genuinely interested in your take on it.
