I wish this comment were true, because this would mean political parties actually use knowledge and information to encourage people to vote for them. In the democratic elections I am exposed to (UK, US), this could not be further from the truth. Further, I think targeted marketing will always lean away from information and into exploiting emotional responses. A reduction in a bombardment of targeted marketing is a positive thing.
However, there should definitely be exemptions, as political information basically just means anything that matters. I feel that ads must have a clear intention to inform, not sell, when it comes to politics.
