I decided to make a shortlist of five each.
Clinton's Shortlist:
evergreen (attack dog, left-wing, gender)
IceSpear (devoted fan, PA, Trump was gonna win WV & OK anyway)
RR1997 (shows bipartisanship)
Virginia (see LLR and dingojoe's reasoning)
LLR (Gank dat youth vote with a youth vote, boi)
Trump's Shortlist:
President Johnson (devoted fan, shows bipartisanship)
Sprouts (PA)
Seriously? (attack dog, see dingojoe's reasoning)
Sanchez (see LLR's reasoning)
Classic (reassure former Cruz supporters)
I felt StatesPoll would work better as Trump's pollster than as his running mate.
I probably got taken off the shortlist because I can't tell what that means
