Actually, this seems like a very good pick to me. Foreign policy has long been Joe Biden's area of focus, and he's been a leading voice for restraint and diplomacy within the Obama administration. He's a solid counterbalance to some of Clinton's other advisers' (Powers, Nuland) hawkish tendencies, and has years of experience in both the Senate and executive branch in the field.
Unfortunately, he publicly ruled it out when the news broke: http://www.cnn.com/2016/10/28/politics/ ... e-clinton/

Don't believe the gender tag. I was born intersex and identify as queer, girl-leaning. So while I can sometimes present as an effeminate guy, that's less than half the time and if anything I'd prefer it say "female" of the two choices offered. I can't change it though, it's bugged.
