I expected something like this, but unfortunately I don’t think it’s because of conservatives “returning to the fold”.
I think it’s Democrats registering as Republicans in states where party registration is required to vote in the primary, so they can screw with the primary results - i.e., vote for Huckabee or Ron Paul or whatever.
But don’t you think there are Republicans crossing over to vote for the most unelectable Democrat in the primaries? If I could, I would.
I can't really think of any good (or nefarious) reason people would do as you suggest in something like this.
I honestly don't think your conspiracy-type suggestion would really impact a study such as this even if it did rely on voter registration.
These figures are not based on voter registrations.
“These results are based upon tracking surveys of 15,000 adults per month. The margin of sampling error is less than one percentage point, with a 95% level of confidence.”
This is just a public opinion poll and may or may not have anything to do with registration. Dems cross-registering can still tell Rasmussen the truth.
