From a European perspective, it is a bit interesting to see it being described like that. Anti-prostitution has become a rather large far-left political priority, with the right and far-right taking opposition. In the far-left perspective, prostitution represent a form of slavery. For similar reasons, anti-pornography laws are generally proposed from the left side of the political spectrum, and then naturally opposed by the right.

It should be added that while typical evangelical Christian voters are sought by right-leaning political parties, voters of the second largest faith is generally sought by left-leaning political parties. This is currently very noticeable given the a specific conflict in the world. Religious voters and political parties that want to cater to those voters are no longer limited to left or right.
