CO/PA
Even though Obama hasn't had the big double digit leads in CO he has had in other states, the McCain camp considers it gone (citing early voting and the Dem registration effort in the state). Evidence of the campaign's priorities can be seen here: i.e., forget CO and concentrate on PA. The campaign also seems to consider—countering the CW for much of the year—NM and/or IA more doable than CO, although neither NM nor IA have looked great in public polling (NM at least had one recent poll at 5, while IA's closest recent poll had it at 8). Anyway, all of this is by way of saying that my strategic advice a while ago to forget PA and concentrate on CO seems to have been exactly wrong (not for the first time). The McCain resources poured into the state, Murtha's comments, and Obama's bitter remarks appear to be keeping it within the realm of possibility.
