It is the whole package
Her "Charitable" foundation
Her questionable financial supporters
Her claims of doing the people's interest when she is obviously a right wing (republican?)
(I have always insisted that the left wing exists only to do the right wings dirty work)
Her obvious lying, She is a proven bull shit artist of collossal magnatude
Then you add the email crap which (whether or not it was treasonous) was a complete security violation.
Do not distract yourself arguing single components of top secret communications, look at the big picture and the mentality/attitude behind it.
Is this who you want steering the ship?
