Hillary really is incompetent.

I have several email accounts that I check on my iPhone.  Why would anyone need multiple devices?

Burn. RT @baseballcrank: So Hillary isn't capable enough to handle two email devices. Where does that set the bar? pic.twitter.com/GkSrQn80mK

Sara Palin probably had more than one device because one of the devices was owned by the government and the other was personal. She may not have been able, by policy, to mix email accounts on devices.
Nothing is ever straight with this liar.
