If Rasmussen was spooked into changing its formulas by the lopsided Pan Atlantic poll, there's no sign of it in their latest results:
Tom Allen (D): 42 (42) (42) (38)We're talking zero movement from last month's numbers.
Susan Collins (R-inc): 49 (49) (52) (54)
UPDATE: At Pollster.com and elsewhere, some commentators are characterizing the result as a ten point advantage for Collins--because Rasmussen lists a breakdown including leaners (53-43) with the poll.
But since Rasmussen has never included leaners before--and I'm still not sure why they did this time--I think it makes more sense to stick with the raw numbers. Which puts things at 49-42.
