Republican 1st district congressional hopefuls Mark Sanford and Curtis Bostic said today that gay marriage and civil unions should be settled at the state level, not by U.S. Supreme Court rulings.

Their comments came as they made their final joint appearance in Charleston, a half-hour debate carried live on WCDB-TV’s Beyond the Headlines program and moderated by Brad Franko.

The issue of gay marriage has made national news this week as the Supreme Court heard two related cases, but it has not been a big issue in the Republican primary to date. Both Sanford and Bostic said they support a traditional definition of marriage as between one man and one woman.

Bostic said he would support a Constitutional amendment to that effect, while Sanford said he viewed marriage as more a religious sacrament than the business of the state.

GOP voters go to the polls Tuesday to decide whether they want Sanford, a former governor and congressman, or Bostic, a former Charleston County Councilman, to be their nominee for the race to fill the House seat vacated by U.S. Sen. Tim Scott.

The winner faces Democrat Elizabeth Colbert Busch and Green party candidate Eugene Platt on May 7.
