Rasmussen likely to show Romney +5- +8 ahead of Obama in the next several days

Creating a virtual bounce doesn't actually make it more likely for Romney to get elected President. So I doubt there's any insidious partisan motivation.

Rasmussen probably thinks we will actually see an R+4 electorate. I greatly disagree, but I suppose it's not an impossible outcome.

Rasmussen has a much better record on presidential elections than congressional elections. It's probably because turnout is higher and robo-calling works far better (which is what they do).

Which is why this R+4 doesn't make much sense. Though a possibility is that the R+4 actually IS the convention bounce.

Rasmussen screwed up because robo-polling lower-turnout races has severe shortfalls.

Nate Silver, on average, found that Rasmussen polls tend to be 1.5 points more Republican than the average poll. Which is hardly hackery. It's perhaps wrong, but hardly hackery.
