I would argue that Trey Gowdy and Nikki Haley are not "POS republicans". It is possible you don't agree with their policy ideas, but they aren't purposefully obtuse, ignorant, racist, or evil as defined by Sys.
This thread is probably more for public figures, but I would toss my hat in the ring here. Mostly because I am a registered republican but IMHO I am not a POS.
