It will depend on what precincts in those counties are still out. Based on the percentages and converting to raw numbers that would be a 30k vote edge to McCaskill. If these are the inner city that would probably take it towards 40-45k. The other counties should likely break Talent.
OK, so worst case now -- She pulls into a tie based on those counties -- and that leaves the 0% counties, which "SHOULD" trend toward Talent.
