And
here's why those who care about polling ACCURACY take a very dim view of Rasmussen Reports:
Rasmussen’s polls have come under heavy criticism throughout this election cycle, including from FiveThirtyEight. We have critiqued the firm for its cavalier attitude toward polling convention. Rasmussen, for instance:
- generally conducts all of its interviews during a single, 4-hour window
- speaks with the first person it reaches on the phone rather than using a random selection process
- does not call cellphones; does not call back respondents whom it misses initially
- and uses a computer script rather than live interviewers to conduct its surveys.
These are cost-saving measures which contribute to very low response rates and may lead to biased samples.
Rasmussen also weights their surveys based on preordained assumptions about the party identification of voters in each state, a relatively unusual practice that many polling firms consider dubious since party identification (unlike characteristics like age and gender) is often quite fluid.
The discrepancies between Rasmussen Reports polls and those issued by other companies were apparent from virtually the first day that Barack Obama took office. Rasmussen showed Barack Obama’s disapproval rating at 36 percent, for instance, just a week after his inauguration, at a point when no other pollster had that figure higher than 20 percent. (edited to emphasize bullet points - wording was not changed - and to add underlining)
As can be seen above, Rasmussen is sloppy - computer scripts can't tell if the one who answers is a 12 year-old kid, and by not calling cell phones skews towards older participants, and as far as I can tell, there's no real effort made to ascertain the party affiliation of the participant. What's more, pay attention to the underlined portion. The participants answering could themselves be illegals who of course can't vote, but Rasmussen isn't verifying who the participants are - instead, they're weighting their surveys based on PREORDAINED ASSUMPTIONS about the party identification of voters in each state.
In other words, Rasmussen Reports is the poster child for Mark Twain's, quip that there are lies, damned lies, and statistics.
