There is so much wrong with the BERN app BEYOND the fact that earlier today, voter IDs/Driver's license numbers were exposed for 150M voters...

a) you only need to know a person's state to find out what city they are registered to vote in.

great for stalkers and domestic violence perpetrators trying to track down victims (and for helping to continue disenfranchising DV victims from registering to vote)

b ) not requiring any kind of confirmation that the new users registering for the service confirm that they are American citizens - anyone overseas can use this to find changes in voter rolls based on age and location alone.

c) instructing someone to hand their phone over to a total stranger just seems like a really stupid idea.
