A new Daily Kos/Research2000 survey finds Arkansas Sen. Blanche Lincoln (D) leading potential Republican opponents, though she carries just a 43% approval rating against a 49% disapproval (Sept. 8-10, 600 LV, MoE +/- 4%).

Many expect the two-term senator to receive a boost after winning the Agriculture Committee chairmanship last week, but she appears headed for a competitive re-election nonetheless. That's a far cry from her fellow Arkansas senator, Mark Pryor, who faced no GOP opposition last year. Other approval ratings for Democrats in the state: Pryor 50 percent, Gov. Mike Beebe 66 percent, and President Obama 41 percent.

Lincoln wins as little as 44% support against State Sen. Gilbert Baker, who is an unknown to 73 percent of voters. State Sen. Kim Hendren and businessmen Curtis Coleman and Tom Cox have even less name ID, yet enough undecided voters keep Lincoln sub-50%.
