in addition to previous discussions on here about polling battleground states only, there is another thing wrong with these polls.
The first question asked is, “Who are the 19% undecided?” What is there breakdown as far as demographics and party ID? If they are mostly DEM, you might figure most will break for Obama. Those are the group in the poll to follow up with many more questions.
Given that fact this is an adult/registered voter poll, I would imagine most the undecideds will stay home.
