If Ayn Rand had invented Paul Ryan, it would have been as a villain, I think. That's based on his views on abortion. Rand was very explicit in her condemnation of Ronald Reagan, saying that anyone who opposed the right to abortion could not claim to be an advocate of individual rights, and therefore had no philosophical foundation for a defense of capitalism; and Ryan is if anything worse on abortion than Reagan was. She described the idea of a prenatal right to life as "vicious nonsense."
