North Carolina Democrats head to the polls in just three weeks to choose a candidate to face Sen. Richard Burr (R) this fall. The national party has long considered Burr vulnerable, but failed to recruit a top tier candidate. A new Public Policy Polling (D) survey shows nearly half of Tarheel State Democrats still undecided about the candidates who are running, led by Secretary of State Elaine Marshall and state Sen. Cal Cunningham.

Democratic Primary Election Matchup
(401 LVs, 4/8-11, MoE +/- 4.9%)
Marshall 23 (+3 vs. last poll, 3/12-15)
Cunningham 17 (+1)
Lewis 9 (-2)
Other 5 (-1)
Und 45 (-2)

Marshall appears to be the most well-known candidate, with a 32 percent favorable rating. A whopping 85 percent of voters had no strong view of Cunningham, but he's looking to boost him name ID in the stretch run. His campaign launched this ad, its first, in a limited buy this week.

On the Republican side, PPP finds Burr safely ahead of token opposition, with 67 percent of the vote.
