For her this is an improvement against any Republican.
Is the e-mail controversy imploding? If so, the recent 'downer' polls for her will soon become irrelevant, and we will see much more red on the polling maps.
In your dreams!
The e-mail controversy as you call it leaves us with only two possible conclusions:
1) Either she did it for convenience, without thinking about consequences, which makes her incompetent
2) Or she did it on purpose which makes her corrupt
In any case, she is unfit to become President.
The general public is still largely unaware of this scandal, but the more people get to know this, the lower her numbers will be.
