6. Maybe you should read your own post more carefully when you post it.
And maybe you should develop a thicker skin.
This is what you said that isn't true:
"Most Obama supporters don't get polled, they are already Democrats, already union members on some list somewhere, so their phone numbers are excluded from polling."
While it is true that most Obama supporters aren't polled (neither are most Romney supporters -- only a small fraction of any supporters get polled), it is untrue that most Obama supporters don't get polled because they are already Democrats or already union members on some list somewhere and so their phone numbers are excluded from polling.
Just because I didn't dispute any of your other points didn't mean I didn't "take them in." I was just responding to a particular point in your argument that I happen to know is false, having once worked for a major pollster.
