David Plouffe, President Obama’s top political and campaign strategist and the mastermind behind the winning 2008 and 2012 campaigns, wrote a forward-looking op-ed [paywall] in the Wall Street Journal recently about the politics of the future and how they might look.

He touched on how technology will continue to change the way campaigns are conducted – more use of mobile devices, even holograms, and more micro-targeting at individuals. But he also mentioned how people might cast their votes in the future, and that is what caught our eye here at the TrustTheVote Project.

Here’s what Plouffe wrote: “More states will inevitably move to online voter registration and perhaps digital voting. There will be resistance…but our voting system won’t remain disconnected forever from the way we are leading the rest of our lives.”

His last statement – that the voting system will come to resemble more our mobile-device-dependent world – is probably true in the long run.  But it’s going to take time, probably more time than we all would like.  Even though we can bank, buy coffee, and get a boarding pass for an airplane via our smart phones, voting by smart phone is more complicated—hugely more complicated.

When you’re banking online, the financial institution has to be able, absolutely, to identify and verify it is you who authorized (or didn’t authorize) a particular transaction (such as a purchase with your bank card at Amazon.com).  But in the world of elections, the election administrator has to be sure, absolutely, that they can never identify you as the person who cast a particular ballot. It’s completely opposite of online banking because of the sacred assurances of voter anonymity and the secret ballot.

Sure, elections officials should verify you as the individual who is checking in to cast a ballot, but once you have been authenticated, the connection with a particular ballot must cease to exist.  And doing that by your smart phone (or any other digital device connected to the Internet) is beyond non-trivial; it’s downright near impossible.

So, there’s a privacy and technology challenge there.  In other words, we need security of the ballot, but we also need privacy of the voter.  And in the digital world there is an opposite (we call it “inverse”) relationship between security and privacy.

Think about an airport and TSA check points.  If you want absolute privacy, you should be able to walk straight to your gate uninhibited.  If you want absolute security, you should not be able to do so until everything about you has been identified and verified as that exact person with an authorized ticket  to board a plane.

If you think about how awful it would be if your online bank account got hacked, imagine if your state’s online voting system was compromised. Not only could the result be suspect, the fact that an election was hacked would undermine voters’ confidence in our democracy.

So smartphone voting might be a ways off. But in the here and now and very near future, the TrustTheVote Project is already delivering on some of Plouffe’s other visions.

Online voter registration, for example, is already being implemented in many states and through third party organizations. The TrustTheVote Project helped Rock The Vote develop its “Rocky” core software, which operates that group’s nationwide online registration. TrustTheVote helped Virginia implement its online voter registration and our technology powers the search part of the Virginia site, which lets you know if you’re already registered, are at the right polling place, and that your address is up to date. This was all developed with TrustTheVote Project open-source technology that all states and localities can adopt and adapt.

And we’re underway on other innovations—like apps to help you figure out the best time to go to your polling place and apps to help you “check in” to vote, just like the ones you use to get  like you download and print a boarding pass for your flight.

So to David Plouffe, yes elections and campaigns will change in the future.  But it will come step by step and not by a big bang of smartphone voting.
