Research 2000 for the Fort Wayne News-Sentinel (10/16-18, likely voters):
Mike Montagano (D): 40
Mark Souder (R-inc): 45
Bill Larsen (L): 4
(MoE: ±4%)
Hot diggity dog, those are some exciting numbers, and they closely mirror a Montagano internal showing Souder ahead by 44-39.
The same poll has McCain ahead of Obama by 53-38. In an accompanying article about this poll, the News-Sentinel spun that result as bad news for Obama. But when you consider that Bush won this district by a 68-31 margin in 2004, that's an incredibly good result.
Both the DCCC and NRCC are spending heavily to pull this one over the finish line, which is pretty remarkable for an R+16 district. This will be one of the earlier reporting districts on election night, so if Montagano can pull out a win, it's going to be a big night. And even if he loses but comes close, that still won't bode well for the GOP.
