So while I'm not a tin-foil-hat wearing conspiracy theorist, I do note amongst the young technorati something of a double-standard. Surveillance, big data and privacy violations are bad when they're used to infringe social rights, but GOOD when they're used to attack people perceived as infringing social rights... C'est la vie.
But more to the point, single-issue activists ALWAYS misunderstand the voting habits of multi-issue voters. Particularly Republicans, who are not just straight-up conservatives as they are often portrayed, but often socially liberal _fiscal_ conservatives who choose not to vote based on social policy. Turning multi-issue swing voters into single-issue activists isn't a straight-forward process, even if you identify who they are.
Finally, this kind of effort makes the assumption that such voters are simply awaiting the right contact or motivation to write their congressperson and demand action. Whereas, in reality, while activists often view the disengaged as "against the cause", the reality is, in most instances, such voters just don't care about that cause.
