Charleston County's rapid in-migration of college-educated professionals has steadily narrowed Republican margins over the past decade, flipping the county to a modest D+5.7 in 2024 — a striking shift for a historically conservative coastal enclave.

The county's recent history is a story of close margins. The Democratic margin reached ninety-five points in 1936; the Republican margin reached forty points in 1972. Most other elections have been decided by single-digit points.

Charleston County's demographics — a population of 420,264, a 66% non-Hispanic-white share, a median household income of $88,494 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Kane County and DuPage County.
