Lindsey Graham's senate seat is being considered by several individuals, including Nancy Mace and Ralph Norman. However, it appears that Darline Graham, possibly a relative of Lindsey Graham, has been selected to fulfill the remainder of his term and may also run for a full term. The situation is complicated by reports of Donald Trump's involvement, with some outlets suggesting he has backed Darline Graham, while others indicate that Mace and Norman are still considering runs despite Trump's preferences.
