In reply to the question; If Alaska were split in to two states where should the linbe be drawn

 Easy answer for that; if the state were split in two the Panhandle to Lituya Bay and Yakatat would be a new state and the rest of Alaska would be Alaska. The two regions are fairly separate as it is and environmentalists and reasonable people don’t want more, destructive shoreline roads to be built to connect them.

Some people regard the panhandle as too warm to be Alaskan, and at low altitude it is as warm as the Aleutians (that should remain with the large part of Alaska). Juneau or Petersburg could be the capital of the South Alaska and Fairbanks should be the capitol of Alaska- although the people of Anchorage might say it’s too cold there.
