Something's wrong here:
Clinton+2 and +3 in NH and MI, but +13 in the US as a whole ?
That would only make some sense if she destroys Christie in the South while keeping the 2012 Obama margins in the "blue" states.
It probably means that Hillary is doing extremely well on the West Coast (especially in California, but also in Nevada, Washington, Oregon, New Mexico and Arizona), as well as in Illinois and Missouri. She can have created a big shift in Tennessee as well, just like she's currently done in many of the states surrounding it (Kentucky, Arkansas, Louisiana especially).
Even so, I think +13% is probably a slight overration of the actual current situation. It's more like +7-12% I think.
