This is a simple suggestion for how you can help activate all the cell-phone only voters: Text Messages.
They're impersonal and quick, and on most phones you can send one text to a bunch of people. So send a mass text to all the contacts in your phone, and tell them to do the same!
Here's some sample text, so I can get to the 300 character limit:
"Don't forget to vote today! And after you're done, remind your friends to do the same!"
If we can bring out just a few extra cell-phone voters, then we can turn some of these races around!
