I tend to stick with the most reliable pollsters. Oddly enough, Gallup is the most widely known, and recently, the absolute worst in reliability and consistency.
But something has come up in the news, lately - many of the major polling outlets are using a model based on the 2008 election. This is a mistake, and certain to make outcomes look favorable for Obama. I think this is a deliberate ploy to mask support for Romney in an attempt to weaken support and depress the vote.
I don't work with opinion polls, but I have been working on surveys most of the last 22 years. Something, some of you know - polls are only as good as the model it is based on - the "methodology". If they only ever polled campus students or Democrats, they wouldn't need answers. Before you conduct your sampling - your calls - you need to have an idea of the universe you are drawing from.
I wish I could tell how many times I've heard the stupid retort of - "they can't ask everyone, so how can they know?". Well, that is precisely the entire point of a survey - correctly ascertaining the whole by looking at a part.
If you are trying to learn how people will vote, you have to determine what group you are collecting data from. For example, there's really no point in asking someone who can't vote - such as someone under 18 or someone who is not a citizen. There's also no reason to ask someone who is not registered to vote - not if you are trying to learn the outcome of an election as opposed to how popular a candidate is. But you also have to know the makeup of your sample - how many do you expect will be women, what is their party affiliation, what is their age. You have to add in the likelihood of getting answers - for example, some polling agencies have determined that Thursdays are the night best for telephone calls, because if you call on Friday or Saturday night, you have very little chance of finding young singles at home. If you call in the middle of the day, you're just going to find stay-at-home moms, retired people and unemployed people.
And so on.
When you're done, you weight the results according to the data you have. If out of a large group you get say, only a few Republicans, but you know there should be 35% of your group - you give them more weight. If you have far more women or youth, you give them less weight.
HERE is the problem:
What if your data says - there's only 29% Republicans? And your random sample shows more? You diminish their contribution.
The problem with these polls is, many of them assume the turnout this November will be JUST LIKE four years ago. And that year was very different from 2004, 2006, and 2010. ANY sample based on that assumption will absolutely show a MUCH greater result for Obama.

So, for now, ignore polls. Vote as you want. Try to find out more about your candidate rather than how he's doing on the back stretch.
