  •  The sample has to be representative (0+ / 0-)

    of the population as a whole.  If Rasmussen started cutting corners like that, then their reputation would suffer.

    Together, we will turn promises into action, words into solutions and hope into reality.

    •  No, the sample has to be representative of.... (0+ / 0-)

      ....their target: likely Democratic Primary voters.

      They've got their ass covered if they sample Democrats for opinions from likely Democratic Primary voters on a Democratic primary.

      It's a very narrow sample, but it's valid in that narrow definition. Doing otherwise would more than triple the cost of the survey. A little over 1/3 of voters self identify as Democrats.  Since non-Dems are less likely to vote in Democratic Primaries than Democrats, they'd have to sample a hell of a lot more non-Dems to find all the likely Dem primary voters to make their sample quota.

      •  If they're going to vote for Obama (0+ / 0-)

        they are likely Democratic voters.  Otherwise, they can't vote for Obama.  The sample of voters has to represent the population.

        •  Get real. (0+ / 0-)

          Rasmussen can save heaps of money by sampling Democrats and still accurately claim they have a sample of likely Democratic primary voters.

          Because a sample of Democrats will yield a sample of likely Democratic primary voters.

          If you're going to claim that Rasmussen will spend more money to take it one step further than that, then present some evidence that backs up your claim.

          •  This is a waste of time. (0+ / 0-)

            Please go read up on polling, sampling methods, and the defintions of sample and population.  I can't have a discussion with you if you don't understand the methodology of polling.
