As we know from GWB, all one need do is gain the majority,
Take this as coming from an Obama leaner or take it as something coming from a neutral observer.
How does one do such a survey by picking and choosing various polls?
Various polls phrase their questions in different ways, thus the question if one took a Zogby poll asked of New Yorkers and a Harris poll asked of New Yorkers would the results automatically line up?
"Would you vote for John McCain is a different question than would you consider voting for John McCain, thus to suggest that one question used in Texas is comparable to the other question used in Maryland, offers some real concerns about how they measure anything accurately
Example:
What are methodological errors?
First, there are many ways a polling can give misleading results due to poor methodology. For example, the phrasing of the questions is known to influence the results. Consider the following options:
- If the Virginia Senate election were held today, would you vote for the Democrat or the Republican?
- If the Virginia Senate election were held today, would you vote for the Republican or the Democrat?
- If the Virginia Senate election were held today, would you vote for Mark Warner or Jim Gilmore?
- If the Virginia Senate election were held today, would you vote for Jim Gilmore or Mark Warner?
- If the Virginia Senate election were held today, would you vote for Democrat Mark Warner or Republican Jim Gilmore?
- If the Virginia Senate election were held today, would you vote for Republican Jim Gilmore or Democrat Mark Warner?
- If the Virginia Senate election were held today, for whom would you vote?
These questions will all get different responses.
Second, the sample may not be random. The most famous blunder in polling history occurred during the 1936 presidential election, in which Literary Digest magazine took a telephone poll and concluded that Alf Landon was going to beat Franklin D. Roosevelt in a landslide. Didn't happen. What went wrong? At the height of the Depression, only rich people had telephones, and they were overwhelmingly Republican. But there weren't very many of them. Even now, telephone polls miss people too poor to have telephones, people who don't speak English (well), and people scared of strangers or too busy to deal with pollsters. These effects could systematically bias the results if not corrected for.

When you use a mix of polls to present a conclusion how are you assuming the difference in the way the different pollsters (neutral or not) phrase their questions does not throw off the consistency of the results?
I understand if you want to shoot me because I lean toward Obama at this point and because of that any of my responses are simply knee jerk reactions, I would also understand if you had the same questions I have about how this offers an accurate comparison.
Suppose I wanted to illustrate something. I could look to a plethora of polling information and pick and chose the poll whose results helped me illustrate what I wanted to illustrate.
If Zogby and Harris both did polls in all states, but because the questions on the same subject they posed offered the potential for a different result as offered in the methodological errors discussion above, why wouldn't I pick the poll results that suited my illustration.
Say the "same" question was asked in Texas by Zogby and Harris, but because of the way it was posed or phrased, candidate Cat in the Hat came out "positive" in Texas in the Zogby poll, but came out "negatively" in the Harris Poll.
All I need do then is select the poll that showed the candidate I supported or did not support gaining either positive or negative results from state to state. If I wanted a desired result.
If I wanted the Cat in the Hat to look positive, I would choose that poll (of the number of polls done in each state) that showed a positive result and discard the polls which offered a negative result. Looking to make the Cat in the Hat out to not be so positive or find negative results, I could simply select the poll that offered that result.
This may or may not be the case in this polling. I cannot find any reference to who put it together, not that who put it together would necessarily legitimize or present an intentional bias, but as with any investigation, the more one knows the more one can consider.
