Clinton falls in the polls while controversies pile up going into September

Hillary Clinton saw a significant drop in support nationwide in polling as Donald Trump took advantage further controversies mounting against the former secretary of state.

Clinton's lead over Trump has shrunk to only four points nationally over the course of a few weeks, according to the latest Real Clear Politics average. The billionaire businessman has even taken the lead in one national poll where he is sitting at 40 percent to Clinton's 39 percent in the latest Rasmussen report and Reuters/Ipsos.

In another national poll, which previously showed Clinton with considerable 7-point lead, Trump now only trails by 2 points according to the latest Morning Consult poll released on Sunday.

The national polling suggests the race is less predictable than it was earlier this summer. Clinton was once favored by a nine-to-one margin over Trump by the politics prognostication team at FiveThirtyEight, but she has a roughly 70-percent chance of winning over Trump's 30 percent going into September, according to the most recent polling.

The recent decline in support for the former secretary of state comes on the heels of swirling controversy surrounding the Democratic nominee's continued connection with the Clinton Foundation.

The New York Times' editorial board came out harshly against Clinton, saying she has an "ethical imperative" to cut ties with the foundation.

The paper made the call following an Associated Press investigation that detailed a series of meetings that suggested possible corruption in the relationship between the State Department and the Clinton Foundation during Hillary Clinton's time as the U.S. secretary of state.

While the Times acknowledged the "pay-to-play" allegations from Trump have not been verified, the article did state that "the emails and previous reporting suggest Mr. Trump has reason to say that while Mrs. Clinton was secretary, it was hard to tell where the foundation ended and the State Department began."

The onslaught of negative attention for the former secretary of state continued into the first days of September with the release of the FBI's report on the Clinton email investigation. The report found that Clinton used a 13 individual devices to send emails, and that some of those devices were destroyed by "breaking them in half or hitting them with a hammer."

Following weeks of controversy, including a hefty campaign shakeup, Trump seems making up ground and capitalizing on Clinton's poor poll number ahead of the first presidential debate in late September.
