Cue the surge  of Bernie Sanders and Joe Biden, with Biden still not an official candidate:
Support for Hillary Clinton among Democrats plunged between July and mid-September, according to a new new ABC News/Washington Post poll released Monday.
Clinton was the preferred choice for 63 percent of Democrats when they were polled in July. But in the new poll, her support sits at just 42 percent, a 21 percent drop for the frontrunner.
Support for Vice President Joe Biden and Sen. Bernie Sanders, I-Vt., also surged over the last few weeks. Sanders jumped form 14 to 24 percent, and Biden rose from 12 to 21 percent.
