That, as I have repeatedly demonstrated, is simply not true. And it's clear you understand that, because you have never in your postings EVER provided a link to ANY poll taken within 50 days of the election showing McCain/Palin up by 10 points.
RCP has virtually all the respectable polling data here General Election 2008.
The last poll that has McCain in the lead is the GWU/Battleground poll, taken September 21-25, 39 days before the election, and that was a 2% lead (less than your "4-10", so it doesn't count). F&M had a poll ending 9/21 with a 2% McCain lead as well.
You have to go back to almost 60 days before the election to find any other polls with a McCain lead. Two polls on 9/11 at +4, and a USA Today on 9/7 with a +10 (That was immediately following the GOP convention).
But the +10 was an outlier, the average through that period never got better than 2.9%, and that was all convention bounce; Obama was back in front by a week after the convention, and it had nothing to do with Mitt Romney.
Polls:1, Delusional Freepers:0.
