that was susan goldwater on march 21st, 2016. >> yeah, right. right. well, i think there's something to be said for that. but at the same time, goldwater was a practical politician. he was not just a man of principle, which he was, the conscience of a conservative, but he was also a practical person. and he would have said, wait a minute now, 63 million people voted for this guy. why? what is he doing? i think that he would begin saying, well, let's see now, supreme court nomination, deregulation, tax cuts, strong military, national defense being built up, being concerned about trade that is not just free, but fair. i think barry goldwater would have applauded all those things. i'm pretty sure he would have. at the same time, he probably would have said something like, well, why didn't trump's mother wash his mouth out with soap and make him understand that we don't need a potty mouth, except goldwater would not have used the word "potty." >> host: how did you become known as a conservative historian, or the historian of the conservative?
