Braun Research for the Rutgers-Eagleton Institute of Politics (9/23-26, likely voters, 8/5-8 [RVs] in parens):
John Adler (D-inc): 41 (31)
Jon Runyan (R): 39 (25)
Peter DeStefano (I): 6 (4)
Undecided: 14 (34)
(MoE: ±5.4%)
Braun offers a number of alternative takes on these numbers, including a sample of just registered voters (which included a "not voting" option), in which Adler beats donkey-powered ex-NFLer Jon Runyan by 40-31. Also note that before including tea-stained indie Peter DeStefano in the mix, Braun tested the race as between Adler, Runyan, and a "Third Party" option; in that match-up, Adler beats Runyan by 44-38. It's interesting that once a name is plugged into the Third Party column, a dent is made in Adler's margin. It would help if some of these teabaggers were a little more notorious...
