When will South Carolina become a swing state?

[OneJ]

South Carolina is one of those weird states in which its kind of steady in its voting pattern. I think Joe Cunningham's win in the 1st district was more a reflection of the national environment being more Dem in 2018, and if you look at the turnout numbers in the 1st district compared to 2016, it was much lower from what I remember off the top of my head. However, at the presidential level, it has been quite steady. Keep in mind that SC also had a long serving senator who was a Republican ahead of entire South's shift to becoming more Republican than in the 70s-80s (Strom Thurmond). So the answer is not anytime soon, but possibly in the 2040s depending on demographic shifts. At least that's my take. And demographic shifts aren't always a given, because they can go the other way too.

I mean 2018 is a midterm year. It’s normal for turnout to be a lot lower in midterm year than a presidential one.

There is no real reason to believe that this state will become more D friendly in the future (and no the fluke victory of Cunningham is not a real reason)

1. The black population is not growing faster than the white population (contrary to GA where Atlanta is a magnet for a lot of black people from the Midwest)

2. You have a large influx of older, white and generally conservative leaning voters, of course these voters are more democratic than SC born white voters but they are still voting by a 2 to 1 margin for the GOP

3. You don’t have a large metropolitan areas with many college educated voters which would give D a place to prosper

South Carolina shows no important demographic change, unlike GA and other states. I see SC as likely R into at least the 2030's, unless an ideological shift occurs.

After Lindsey Graham retires, as he is making it a Solid GOP state.

The only hope is for cities in heavily R areas to start trending D, which is happening up here in Greenville and Spartanburg, but not so much in places like Myrtle Beach

Not sure that it ever will with the retiree influx to the coast, however it could become winnable in future Dem wave years since those moving in appear to be more elastic than those who grew up there.

Mostly this.

This literally makes less than zero sense.
