Lindsey Graham's sister wins Republican primary to contest Senate seat in November - BBC

Graham had never run for elected office before this race. She entered the Senate as a temporary replacement after her brother died suddenly in July, and Tuesday's primary result means she'll now carry the Republican nomination into the general election.

Trump's decision to travel to South Carolina and stump for Graham is drawing attention beyond the state's borders. Her win is being read widely as a measure of how much sway Trump still holds over Republican primary voters when he puts his name behind a candidate.

For folks in Lubbock watching national politics, this one carries a few layers worth tracking. Lindsey Graham was a fixture in U.S. Foreign policy debates for decades, and whoever wins his seat will inherit real influence on those same issues. A candidate who entered the Senate without a single prior campaign now holds a major party's nomination after one primary, going from political newcomer to statewide standard-bearer in a matter of months.
