Excite has a daily poll
"The presidential election is less than one week away. For whom do you plan to vote?"
Bush 52% => 10970 votes
Kerry 41% => 8660 votes
Excite is different. You cannot clear your cookies and vote more than once. I believe it is based on your login. Only those with a login and password can vote. For an internet poll I have some faith in this one.
Also, if you check out the sites where you can bet money on the election you will see that betting on Kerry will pay off more than twice as much as betting on Bush. Those paying out the winnings will use un-biased polling to determine odds since they are more interested in making money than trying to create momentum for the Dumocrats.
