Political belief has very little do do with it, that is unless you know who's going to be our political masters in 10-20 or even 50 years from now.
And i hate to shatter your illusion but the government, or rather people in power or seeking power are very interested in you, if they weren't they wouldn't have spent so much money on getting to know you, your likes and dislikes, and whatever else they glean from peoples "social" media presence, it's not about if you've done anything wrong or not, it's about predicting and/or targeting you with the most effective messaging to get you to buy something, in the case of 'government' (people in or seeking power) it's about whether to bother spending money on directing advertising at you and what's the most effective way of getting you to vote for them.
Essentially they want to use the same techniques that the likes of Amazon, Facebook, Google, and others use to get people to click on and buy things they don't necessarily want, and they're not restricted by silly things like advertising standards.
