THE HILL: September Disaster For Clinton Campaign.

Hillary Clinton’s health problems — and, in particular, the shocking video of her being helped into a van on Sunday — are the worst developments yet for a campaign that has hit a serious rough patch.

Before the health drama, polls were already tightening, and the Democratic presidential nominee had delivered a semi-apology for asserting that half of Donald Trump’s supporters came from a “basket of deplorables.”

Democrats aren’t in full-on panic mode just yet, but they are worried that a race that had looked comfortable only a few weeks ago is now seriously competitive. And they expect to be on edge for much of the next week, until the first polls appear indicating how Clinton’s battle with pneumonia is affecting the contest.

Woolsey, who served as director of the CIA from 1993 to 1995 and describes himself as a life-long Democrat, praised Trump’s commitment to ending defense budget cuts from sequestration.

He said he can’t support Democratic presidential nominee Hillary Clinton because of the controversy surrounding her use of a private email server as secretary of State.

“She demonstrated a complete lack of understanding and an inability to lead the agency she headed in such a way as to maintain its mission and security,” Woolsey said in a statement.

“Based on the emails thus far released we know that Secretary Clinton also lacks the ability to lead her senior managers while complying with and maintaining the basic protocols designed to protect our government’s sensitive and classified information. Mr. Trump understands the magnitude of the threats we face and is holding his cards close to the vest.”

Hmm.
