Not the results, the sample. If the sample is drawn randomly from the population in question, and is of large enough size, its composition can be relied on to a known degree of uncertainty to be representative of the population from which it's drawn.Quote from AK Forty Seven:
If the results are random absolutely

Of course they do, mathematically they must. Using example only numbers, 30% of the population will vote, 50% could have voted, and the rest can't vote at all. If you took a large, random sample from the census, and eliminated all those in the latter category, you're left with a sample of "can vote". Randomly sample that and ask each of those drawn, "are you likely to vote?" Eliminate those who say, "no". The remainder, if you started with a large enough initial sample and have ended up with a statistically reliable (the validity is determined by the randomness) sample size, you also have a representative sample, whose members will be (this can be mathematically demonstrated) a proportion of the general public, and a proportion of the general public who can vote, and a proportion of the general who can vote and who will likely vote.Quote from jem:
The public does not show up to vote in proportion to the the population. (there are a lot of dems who don't vote and dont exist)

Reexamining the results, after the event occurs, you should see, with a variance of "plus or minus three percentage points", that your sample voted just like the general population (who can vote and did). This is elementary statistics.
Now, for those in the sample you mention, of course not all dems will vote, but neither will all reps vote. As for nonexistent members of the sample, maybe, maybe not, prove it. From what I can see, the various polling agencies are bouncing around a mean and I'm not seeing a consistent bias that would indicate anything besides random sampling. Admittedly, I'm only glancing at the results at this point, it's early.
Quote from atticus:
Bain Capital, under Romney, took $342MM out of Dade Behring after they took the company out. Less than 18 months later the dearth of cash forced it into bankruptcy. The Dem establishment are falling over themselves producing TV ads on this and other deals done by the antichrist.
He's summarily fcuked. No way in hell Romney gets in. it's laughable to comprehend.
