If you've had your doubts about the likely voter models out there in the field, this should give you slight pause.
http://story.news.yahoo.com/news?tmpl=story&u=/ap/20041019/ap_on_el_pr/winning_the_new_voters&cid=694&ncid=2043 Report: Dems Register More New Voters in Swing States
The AP reports that Democrats have registered more new voters than Republicans in these swing states:Arizona, Iowa, New Mexico, Nevada and New Hampshire. In Florida, they are tied.
There are no numbers for Ohio and Pennsylvania. No mention is made of Colorado.
At the same time, it's interesting to look at where the polls were for the same time four years earlier on October 18th and 19th:
Polling Firm Date Bush Gore Bush-Gore ABC 10/19 48% 43% +5% Gallup 10/19 50% 40% +10% Opinion Dynamics 10/19 45% 42% +3% Reuters/MSNBC 10/19 44% 44% 0% Voter.com 10/19 44% 39% +5% ABC 10/18 48% 44% +4% Gallup 10/18 49% 39% +10% NBC 10/18 45% 43% +2% Reuters/MSNBC 10/18 44% 43% +1% Voter.com 10/18 44% 40% +4%
Note that not a single one of these polls gave any advantage to the actual winner of the popular vote.
