Polls are not completely meaningless...

As long as you understand that they only provide a piece of the picture.
Three things that have to be considered when reviewing the polls:
1. Enthusiasm. It takes nothing to tell a pollster "I like candidate A"... But it takes a bit more to go wait in line and vote for him. Some polls actually track enthusiasm, and those polls show overwhelmingly that Obama support is FAR more enthusiastic than McCain support... This should slant the numbers in Obama's favor on November 4.
2. Ground Organization. A team on the ground is needed to get people to the polls, remind people to vote, turn out and convince last-minute support, make sure all supporters are registered within the necessary time frame, etc... The more volunteers and the better the organization, the more their support will be over-represented. This should slant the numbers in Obama's favor on November 4.
3. Cell Phones. The polls only do land-lines, not cell phones. By excluding cell phones you are excluding the young professional crowd and almost all college student respondents. Under-representing these groups would tend give an impression that McCain is doing better in the national polls, as only older and more traditional people carry land-lines. This too, should favor Obama on November 4.
I tend to think the polls are a nice indication, and probably will fall within the margin of error... I just think that the margin will slant heavily towards Obama... So, for instance, with the new Ohio poll that was released Sept 2 (Opinion Research): Obama 47%, McCain 45% +/-3-5%... I think of this as a current snapshot that shows that if the vote were held today, Obama would get somewhere between 47-52%, and McCain would get somewhere between 40-45%... and they'd split the remainder 50-50...
That is, of course, my interpretation... and we won't know until the votes are cast.. but I think having a tool to help see the current dynamics of the demographics does help... You just have to determine what other influences there are, and how those may favor one candidate or the other... and factor that in.
I think it's pretty obvious that Michigan will go Obama's way... He's led every single poll there since Hillary dropped out. It will be close, but as long as his ground team does their thing... he'll win.
Both Dakotas, Montana, Indiana, North Carolina, and Mississippi are all in play this year. Yes they represent a strong uphill battle, but Obama should spend some resources on a strong ground game in each of these states to make McCain and Palin waste resources they don't have. Spending very heavily in NC and MS will also help secure two more (very closely contested) senate seats... as the get-out-the-vote operations for Obama help all democrats.
