My sister once asked me when I had turned into a Liberal, and I realized the other day that I always have been. I always called myself a Republican (conservative), but when you asked me about any single issue I very often held a more or less liberal position on it. I finally realized that when your individual positions are more often liberal than conservative, on a 4:1 ratio or so, you are a liberal.
I kept my life simple, of course, by limiting topics of discussion to those on which I held a conservative view. I think it was Ronald that finally made that untenable. Maybe it was George the 1st.
