It is definitely possible that the opposite of this question occurs. It is possible that a majority of voters might support liberalization even though it would hurt a lot of voters if implemented. This is because people do not always have their best interest at heart. Sometimes, this is because of poor information (people might not realize that something benefits them/affects them) while some other times it is because other factors do not let people see the truth (such as intense ideological or religious feeling).
Personally, I believe that differing political views result in greater political participation because of a persons need to help the side they support win. Take this for example: Republican and democratic parties have come to an issue where they see two completely different solutions. The republicans are scared that if they don't have great amounts of participation, the democrats will win and the democrats are scared of they don't have great amounts of participation, the republicans will win. This need to help the idea they support win drives a greater amount of political participation form both sides and is applicable to any differing political views. Hope this helps! :)
