Chambliss becomes first Senator with own iPhone app

Will this app show the user how the congressmen plans to vote on current bills?<p>Could the user upvote/downvote bills as an efficient way of sharing their opinion. Isn't this what letters and phone calls are turned into at best anyway? A tally.

I wonder what value this provides to his constituents that his website, email, or the existing open Congress app doesn't already do better.
