I think Manchin would only be picked as a Hail Mary if she is trailing and only getting ~25% of white men in her polling. However, the odds that she will need to Sista Souljah the social justice activists have gone up with this week's events at Yale and Mizzou. We'll see.
I also forgot to mention Booker and Patrick, both of whom could help assure continued Obama-level black support and turnout. Booker probably dominates Patrick here because Patrick barely made it out of 2010 in a 60% Obama state and he now works for Bain Capital, which could get very awkward if Republicans run Obama's anti-Romney ads against Patrick.
Isn't Booker too Wall Street-friendly for the base?
