COLUMBIA, S.C. (AP) — Just like the 12 other elections this century, it was a good night for Republicans in South Carolina.

The GOP continues to gain seats almost 25 years after taking control of nearly the entire state government. On Tuesday, they did not lose a single incumbent and likely added four Senate seats to have a 34-12 advantage in the chamber. Democrats had a 14-seat lead back in 1992.

It’s the first time Republicans will have a two-thirds supermajority in the Senate, which assures they can end filibusters with ease. In the House, Republicans held firm with 87 seats in a 124-member chamber with two vacancies. The combination means Republicans can put constitutional amendments on ballots without a single Democratic vote. And in an institution where senators often stay for decades, there will be 13 new members in 2025. Nine of them are Republicans.

The story Tuesday night wasn’t much different than on recent election nights. Republicans in South Carolina swamped Democrats with a huge wave in 1994, taking over the House, and and again in 2000 taking over the Senate.

And the waves just keep coming, claiming more of the state’s political beach even as Democrats chose South Carolina for their first presidential primary this year.

Redistricting helped. Republicans won at least 57% of the vote in every Senate district they controlled at the start of election night.

Over the past eight elections, Republicans have not lost seats in the Senate, and they now control more than 75% of the chamber in a state where Donald Trump has never topped 59% in a presidential race.

Continuing a trend of rural areas getting quite Republican quite fast, all four seats the Democrats lost were outside cities. Four Democratic senators — three Black and one white — were swamped in their rural precincts and a few rapidly growing suburban areas, and the dwindling minority population wasn’t enough to keep up.

The GOP also flipped four sheriff’s and three coroner’s offices from Democrat to Republican.

On Tuesday, nearly 800,000 of the 2.4 million votes cast were Republican straight ticket. The GOP has 21% more straight ticket voters than Democrats. Republicans had only topped Democrats among those voters starting in 2016.
