Poll#1 surveyed

Poll#1 surveyed
3. 39% pro life and 57% pro choice
Poll #2 surveyed

I am not claiming to know which sample size is better or which poll is more accurate. I am also no trained pollster to know if that is that big of a difference. But I think the the more recent survey was a slightly more liberal portrait of Virginia than the survey taken a week before.

But it highlights what I fear, that is just a subtle difference in turnout can change the outcome of this election. If I had to guess who will have better turnout I would have to assume it would be the Obama machine.
