Rep. John Boozman (R), who is set to enter the Arkansas Senate race this week, holds a commanding lead over Sen. Blanche Lincoln (D), according to a new survey by a Democratic polling firm.The North Carolina-based Public Policy Polling found Boozman up 56 percent to 33 percent over Lincoln, according to a survey of 810 Arkansas voters conducted Jan. 29-31. The survey had a 3.4-point margin of error.Boozman isn’t particularly well-known in the state. Thirty-two percent of voters had a favorable opinion of him while 25 percent had an unfavorable opinion and a full 43 percent said they are unsure what they think of him.But voters do know that they aren’t happy with Lincoln’s job performance. Just 27 percent of voters approved of the job Lincoln is doing while 62 percent disapproved and 19 percent said they were unsure.Before Boozman acknowledged he was getting into the race, the GOP frontrunner in the crowded Senate primary field had been state Sen. Gilbert Baker. The PPP poll found Baker led Lincoln 50 percent to 35 percent.
