“After a razor-thin victory by Clinton in Iowa, a blowout by Sanders in the New Hampshire primary and a small margin by Clinton in the Nevada caucuses, Clinton is perched on the cusp of her own significant primary victory in the Palmetto State,” Bruce Ransom, a Clemson political science professor, said in a statement.

Clinton has maintained huge leads in the State for months. An October poll by Clemson found Clinton with 43 percent support and Sanders at 6 percent.

Despite his big deficit in South Carolina, Sanders has drawn close to Clinton nationally, winning in New Hampshire and losing by narrow margins in Iowa and Nevada.

Clinton leads Sanders nationally by 5 percentage points, according to a RealClearPolitics average of polls.

The Clemson poll was of 650 likely Democratic primary voters from Feb. 20 to 25. It has a 3 percent margin of error.
