Oh my god. Hillary is getting a challenger from the heart of the democratic establishment that supposedly loves her. So much for the democratic primary being boring, and so much for Hillary being inevitable. Start crying, Icespear!
Um, no. This is the best thing that could happen to Hillary. Biden running completely changes the narrative of Hillary vs Sanders and makes it a multi polar race. Biden is a serious enough candidate to make the media chill on Sanders, but ultimately not good enough to beat her. Biden also challenges Hillary to become a more personable candidate as well. It just sets her up better in a general election if the primary isn't a coronation.
