@Cycloptichorn,
Thanks, Cyclo, for finding that. You beat me by a few minutes in retrieving the article.
I thought it was interesting that the poll was able to go back to the 1250 people they followed numerous times in 2008.
Here in the 5th District House Race in Virginia, the Dem incumbent Perriello is in danger after just one term. He swept in by 800 votes because of the support of minorities and the young (and an overly complacent Repub incumbent). I see no active support here in liberal Charlottesville from the student Dems.
I realize, hawkeye, that I probably should do a better job of sourcing things I say. I reckon I rely more than I should on my reputation as trying to be balanced on a thread like this one. I will try to do better.
