What the Evidence Shows
The claim states that the president has a net negative approval rating in North Carolina, which means more people disapprove than approve of the president. The search results include multiple news articles discussing the president's approval rating in North Carolina, describing it as having declined or being 'underwater' (below 50%) at certain points.
However, these articles also mention shifts and reversals in approval ratings, indicating fluctuations rather than a stable net negative rating. None of the sources provide a definitive, current polling figure explicitly confirming a net negative approval rating at this time.
Additionally, the Wikipedia link provided does not lead to a relevant or verifiable article on this specific claim. Therefore, while there is some indication that the president's approval rating in North Carolina has been low or negative at times, the evidence is not conclusive or consistent enough to fully support the claim as stated. It is more accurate to say the claim is misleading because it oversimplifies a dynamic and variable polling situation.
