First let me say that OneMan does not have an iPhone (much to the surprise of my father and father-in-law).
Imagine however a cadre of campaign volunteers using iPhones while going door to door. Yes, I know people have used phones and Palms in the past but the iPhone is much easier to use.
The ability to have the campaign worker/volunteer enter voter info in real time that can be reviewed and/or worked. Also the ability to build a more robust application that could change survey and other questions in real time that is usable via the web and via a phone could be a show changer...
Why I am typing this, I need to get coding!
