CBS News reported that South Carolina has been added as a battleground state, although the network still considers the state to be leaning Republican. According to a CBS News video report, the change was described by Anthony Salvanto during an appearance on Face the Nation with Margaret Brennan.
The report identifies Salvanto as covering CBS News elections and surveys. The video summary says he told the program that South Carolina is now counted among the battleground states, while the state is still considering leaning Republican. CBS News presented those two points together, and the summary does not describe any disagreement between them.
The summary does not say what led to the addition or what information supported it. It also does not include polling figures, vote totals, or further remarks from Salvanto beyond the points noted. Readers seeking the reasoning behind the designation would need to consult the full CBS News segment, which was not part of the material used for this story.
The report is a brief summary, and it does not show how the network defines a battleground state or a state that leans one way. Based on the summary alone, the battleground label and the Republican lean are both attributed to CBS News through Salvanto.
No other outlet's coverage of the matter was part of the material reviewed for this story. The CBS News item carries a publication timestamp, but the summary does not state when the appearance itself took place, how long it lasted, or whether other guests joined the discussion.
