SC, MO, AZ (probably), IN and UT are fool's gold for Clinton, unless Trump totally implodes. Obama 2012 + GA and NC are the states she should focus on IMO. These two states are going to be more promising for Democrats in the longer term as well.
She hasn't even visited or spent money in SC and MO since their primaries. It just shouldn't be this close this late into August. This is the third poll to show a low-mid single digit lead for Trump. Pretty damn clear he's imploded, I don't know if completely imploded
