Smerconish: "Real patriots voice opinions based on substance, not smears."

Years of blogging, briefing, debating, and public speaking have driven home to me one point -- a point that CNN's Michael Smerconish articulated perfectly last Friday. Personal attacks reveal the weakness of a person's position on the issues. Rudy Guiliani's recent attack on President Obama's patriotism is merely the most recent example. This is what people do when they cannot rationally defend their substantive beliefs.
