It is because the demographic change (remember they are changing America by changing the people) is far advanced in North Carolina while it is only beginning in South Carolina.

Of course all that will change for SC in a few years as Republicans like Senator Lindsey Graham and Rep. Trey Gowdy are making little to no effort to hold the line in terms of the UN/US State Department Refugee Admissions Program, and Graham himself was one of the Senate ‘Gang of Eight’ that pushed through an amnesty bill for illegal aliens a couple of years ago.
I don’t understand how Rs like Graham don’t see that as the immigrant population grows it will be attracted to the Democrat Party which promises to keep their welfare goodies flowing and will ultimately lead to the downfall of the Republican Party in states like his.
But, it isn’t SC I want to tell you about.

Trump and Clinton going to North Carolina today!

***Update*** November 4th: 1/2 million federal grant to encourage ethnic separation awarded in Raleigh.
I’ve wondered how North Carolina, the land of Senator Jesse Helms, is now a toss-up state and today as both Hillary and Trump head there, we see very clearly that it is a traditional red state turning blue and both parties are fighting for it.
So, I did a little numbers research.  And, I am not saying that there are enough refugee voters to swing the election, but the vast disparity between the states is stunning.  Also, NC has obviously thrown out the welcome mat to illegal aliens. (Note in my previous post that it is clearly in the top ten for the placement of the ‘unaccompanied alien children.’)
All of the following data can be found at the Refugee Processing Center.  And, I found a bit more at an ORR annual report to Congress.
From 1983 to 2001, North Carolina resettled 16,640 refugees, while South Carolina only got 1,925.
Then from FY 2003 to FY 2016 the states break down this way: NC (27,748) and SC (2,042).

Total refugee tally for NC is roughly 44,388 to SC’s 3,967. 

(In between those two documents, I was too lazy to look up 2002, but you get the idea).
So, I am maintaining that it is the influx of vastly more immigrants and refugees to North Carolina than South Carolina that makes the difference—why NC is turning blue and SC isn’t (yet!).
***Update*** And, I should have mentioned all those worker visas for NC, here.
We have a pretty substantial archive on North Carolina and problems there with refugees, go here to learn more. Don’t miss a stunning murder case, contractors not taking care of the refugees, companies looking for cheap labor and posts on how NC colleges lured Arab students, including 9/11 mastermind Khalid Shaikh Mohammed, to the state to boost their student enrollment.
Then I found this stunning. From FY2003 to FY2016, North Carolina received refugees from the following 56 countries. This list does not include illegal alien-sending countries like Mexico and some from Central and South America. Can you imagine the problems with languages in the medical system, the school system and the criminal justice system!

Where were they placed?
I started to look at all the towns and cities and when I got to 35 I quit.  Bottomline, I bet there were at least 50-60 towns and cities in North Carolina that received refugees.  Maybe only a couple in some towns, but they were very widely distributed and surely helped destroy community cohesiveness.
Eight of the nine major resettlement contractors are operating (competing!) in North Carolina. The only one missing is the International Rescue Committee. Go here for office locations.
The wild card for Trump and Clinton is whether the African American community there gets it—that they are being out-competed in the job market by tens of thousands of refugees pouring in to the state. And, if Hillary is elected there will never be a slowdown.
