I base it on observations. For example, I forget who, but there are a few congress people and senators which love to hand out ayn rand books to freshmen. Also there was the chair of the fed, appointed by conservatives who was an ayn rand desciple. Several people on this forum idolize her and her ideology, generally they are on the more libertarian side of conservatism. lots of little observations like that, granted the more I think about it, the more examples I will be able to dredge out of my brain.
