Democratic poll shows tight race between Sanford and Colbert Busch

New polling conducted for Democrat Elizabeth Colbert Busch's South Carolina special election campaign shows her leading both men who will face off for the GOP nomination Tuesday, including former governor Mark Sanford.

The Lake Research Partners poll shows Colbert Busch ahead of Sanford but within the margin of error, 47 percent to 44 percent. Sanford is a heavy favorite in Tuesday's Republican primary runoff.
