I don't think this is going to produce anything worthwhile (much like online comment sections never produce much that's worthwhile), but I wanted to respond to a couple of your thoughts:

> Only one vote per ip + browser + os

You could do that with cookies, but it would be absolutely trivial to circumvent. Someone could submit votes as fast as your server could process them.

> Request some piece of identification (a DL number + State; or a phone number + DOB + Place of Birth?

This will weed out people who are cautious about their privacy, and it also creates a huge ethical responsibility for you. When you're storing sensitive info (like political views) along with PII, you better do a damn good job of securing it. Even though I've been in this industry for 20 years, I still don't do this kind of thing myself -- I hire a security expert to audit my work. Are you willing to do that?

Your only real hope of a one-vote-per-person system is Facebook login. There's nothing else on the web currently that works as well, since you can't legally verify things like DL numbers.
