Political junkies are focused on Donald Trump, but Hillary Clinton’s weakness remains a huge story. Her support among Iowa’s likely Democratic caucusgoers has dropped to 37%, down 20 points since May, according to an Aug. 26 Des Moines Register/Bloomberg Politics poll. Meanwhile, Vermont Sen. Bernie Sanders is up 16 points to 30%, and Vice President Joe Biden, who isn’t even running, is up six points to 14%.
The poll caused great consternation among Mrs. Clinton’s supporters, as it should have. Some of her advocates tried to claim that the survey contained good news, in that the former secretary of state’s favorable rating among Democratic caucusgoers remained at 77%.

That too was polled. Only 2% of Mr. Sanders’s backers said that their decision to support him was because they don’t support Mrs. Clinton.
