What are the unpolled advantages on each side?

[Onlooker]

The Dems seem to have at least two advantages among those who are typically not polled:
- New voters
- Cellphone users

Any others?

What about the Repugs?

[David Dunham]

1. Reps: challenging black voters and Diebold

[Dukakis88]

2. GOP: White separatists holed up in rural Idaho without telephones.

3. Dems will get most of the undecided-they usually break to the challenger

[Ruffhowse]

4. Younger voters are polled less because they are home less often--

and they skew towards the Democrats.

5. republicans are getting a boost from the anti-gay thing in several states

At least some of that increased turnout for early voting is religiously insane homophobes rushing to the polls to keep the children of gay couples from getting health care benefits, and life partners from having hospital visitation rights. That'd be an abomination, ya know.
