They also are in shock that their candidate might be a socialist.
Latest poll has bernie neck and neck with Clinton now.I thought it was too late for Joe Biden to jump in way back in September 2015. As it stands now, Clinton has locked down almost all of the insider support to win the nomination barring some twist. So yeah, it's WAY to late for Biden. I didn't really think he had that good of a chance in the first place. Especially after Clinton kept her cool and held her own in the Benghazi hearings. That pretty much solidified her to be the democratic nominee, barring a Sanders miracle.
