McCain Link Hurts Graham in South Carolina

A new Clemson University poll finds Sen. Lindsey Graham would get the votes of 31% of GOP voters regardless of his primary opponent, while nearly 20% of Republicans said they would not vote for him.

Key findings: GOP voters told the Clemson poll they disliked Graham for: his perceived lack of conservative principles; association with Sen. John McCain (R-AZ) and tendency to compromise too much with Democrats.
