Restricting this to certain lawmakers based on political affiliation on positions is not the right way to go. If one party is more affected than another, they will turn it into a purely tribal issue. (Democrats are lawbreakers who are endangering Republican politicians by releasing sensitive location data! This shows that Democrats cannot be trusted! Why wasn't Clinton's location data released too? Fake liberal news, etc.. etc..) This is easy to spin, and will turn their base against reform.
If you do this, you have to include all lawmakers. This is actually more fair because regardless of who is paying lip service to privacy, the legislature collectively has failed to do anything about it. How do you know those who claim to support privacy really do at all behind closed doors?
What we want is a government scared of its citizens not the other way around.
It might already be illegal, it sounds a little like blackmail.
the party that discloses the information does not need to have demands.
If that’s not enough, some simple data mining to list all their known associates, mistresses (etc), would probably get it fixed.
Sadly, they’d probably just make it illegal to publish data about the ruling class and not the rest of us.
