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.
While Clinton’s support has tanked, Donald Trump’s support among Republicans continues to surge. Trump is now the primary candidate choice for 33 percent of Republicans, a 9 point jump from July. However, six in 10 Americans view him as under qualified to service as president.
Trump leads retired neurosurgeon Ben Carson, who is at 20 percent, an increase of 14 points since July. The high numbers for both Trump and Carson show a support for anti-establishment candidates, as both have never held public office.
Former Florida Gov. Jeb Bush dropped down to 8 percent, down from 12 percent in July’s poll and 21 percent in March. Texas Sen. Ted Cruz and Florida Sen. Marco Rubio both garnered 7 percent, Kentucky Sen. Rand Paul is at 5 percent and former Arkansas Gov. Mike Huckabee and Ohio Gov. John Kasich both followed with 3 percent.
Rounding out the field, Wisconsin Gov. Scott Walker and former Hewlett-Packard CEO Carly Fiorina polled at 2 percent, which is a decrease of 9 points for Walker since July. New Jersey Gov. Chris Christie, former Pennsylvania Sen. Rick Santorum and former Texas Gov. Rick Perry (who dropped out of the race last Friday) each drew 1 percent each, while all other GOP candidates failed to register a point.
The telephone-based poll was conducted by Langer Research Associates from Sept. 7-10, surveying 821 registered voters with a margin of error of plus or minus 4 percentage points.
