Is she really that out of touch? The 'viciousness' didn't just come from the opposition. At that, the vicious nature of her father's campaign was something that was lauded over and over by supporters as 'finally taking it to them', 'telling it like it is', 'not being politically correct', and so on (lather, rinse, repeat). There is no playing innocent or naive in this. When you act like the enemy (as you put it), you are going to become what you hate. Hell, her own brother the other day was calling them 'not human'.
This is the nature of politics and even society today.
Hell, you can talk about a rock on the internet now and it will degrade into a spitball fight.
