Republican, Republican, Republican. For all of my immediate and most of my distant family members.
But are you the kinda South Carolinian whose family were Democrats back-in-the-day or are they of Yankee Republican stock?
Some of my family were. I had one great-grandfather who was a democrat. But the rest had pretty much moved to voting Republican by Eisenhower. I don't know much further back than that, but I assume it's a safe to assume at least some of my relatives were in the almost 99% that voted for FDR.
