Sen. Richard Burr has at least a 10-point lead over his challengers, according to a new Rasmussen poll.
The Rasmussen Reports poll found of 500 likely voters found Burr ahead of longtime Secretary of State Elaine Marshall 48 percent to 38 percent.
U.S. Rep. Bob Etheridge, who has been courted for the race, trails by 48 to 34 percent.
Burr leads Durham lawyer Kenneth Lewis, who like Marshall has officially declared for the race, by even more — 48 percent to 32 percent.
The news isn't all great for Burr.
"Despite Burr’s early lead, however, incumbents who poll under 50% are generally considered vulnerable," the pollster said.
The poll had a margin of error of plus or minus 4.5 percent.
Other Democrats looking at the race include former state Sen. Cal Cunningham of Lexington, former Lt. Gov. Dennis Wicker of Sanford, and Chapel Hill Mayor Kevin Foy.
