I really don't want to see what Trump's ego would be like if next year he's a point ahead of Obama (even at 17 percent to 16 percent.)
There were a few links in the earlier posts in the general questions of the southern strategy.
There was a piece by Matt Ygleisias for the Atlantic.

Sean Trende had written about Eisenhower's success in the South, and the major reasons for the shift.

Matt Lewis wrote about the South's large concentration of rural voters.

I'm not eager to watch a 16 minute video.
As for the Jeet Heer piece (I'm familiar with him; I've quoted two of his articles on the past and the dude has interesting thoughts on comics), it focuses primarily on Trump's support in the South Carolina primary, and on views held by larger minorities of Trump supporters than among typical Republican voters. There is a conflation of racism and xenophobia.
He gives too much credit to the National Review for its influence in making the error of promoting states rights (at the time in an anti-communist context) and doesn't quite explain how the southern strategy worked: Did racists who want liberal economic policies join Republicans because they wanted racist local control? It also neglects that the south has become very different, both in the sense of how long it took Republicans to start regularly winning controls of legislative bodies and governor's mansions, and in terms of how much better the views of modern southerners are than those of the past.
