Liberals taking credit for others’ praxis is their praxis.

Or for the system. If the end result is that an election can be won by buying ads then all the work was for the benefit of the rich.

You're just being pedantic. In mainstream US terminology "Liberal" means left and "Conservative" means right. If you start using terminology beyond that the target audience isn't going to know what you're talking about, and you'll lose them before you even have a chance to make your point.
