Zata3 for Talk Business (Arkansas). 4/14. Likely Democratic voters. MoE 3% (No trend lines)
Blanche Lincoln (D) 38
Bill Halter (D) 31
D.C. Morrison 10
Undecided 20
Morrison is a conservadem who voted for Ron Paul in 2008. While 10 percent for an unknown candidate who isn't spending any money on the race looks hinkey, there could theoretically be a protest vote based on the negativity of the race. Lincoln's camp has been one non-stop smear campaign, while the independent expenditures by the labor unions on the pro-Halter side have been slamming Lincoln pretty hard. Lesser-known candidates have been known to score points by simply being "none of the above".
The Lincoln camp responded to this poll by releasing an internal poll that supposedly shows her up 51-34. The only other outfit to poll since January is Research 2000 for us, which had the race as 44-31 Lincoln. We have a poll in the field right now, and will have new results tomorrow.
