Much better then Virginia.
This is what the margin could have been in VA if Sanders had campaigned there. Then again Clinton has underpolled in the South this entire cycle.
Yeah, probably. If Bernie does very well from here on out but Hillary's lead is simply too big to overcome (as most people seem to expect), his decision to ignore half the Super Tuesday states could very well have been his fatal mistake in retrospect.
If Sanders had targeted a bit in the Upper South (W VA, NE TN, NW AR, NW TX) I think he could have made Clinton's delegate margins a bit more reasonable by actually winning a few congressional districts.
Yup - without question Sanders' biggest strategic error.
