Kos highlights a 1992 article from Ron Paul's self-published newsletter, The Ron Paul Political Report:
Indeed, it is shocking to consider the uniformity of opinion among blacks in this country. Opinion polls consistently show that only about 5% of blacks have sensible political opinions, i.e. support the free market, individual liberty, and the end of welfare and affirmative action.... Given the inefficiencies of what D.C. laughingly calls the "criminal justice system," I think we can safely assume that 95% of the black males in that city are semi-criminal or entirely criminal.
