Where do we define 'north and 'south'? How do western states fit into this picture? I wouldn't be surprised if Hillary Clinton could get close (my definition doesn't include DC, MD, or DE). The northeast will probably never vote Republican again, but that's not necessarily 'the north'.
203: South
190: North
Interestingly, Maryland and Delaware make up 13 electoral votes. While D. C. is clearly culturally northern, Maryland and Delaware have a mix of culture. Not counting them it's an even 190-190 split.
