Abstract: This essay examines how U.S., Germany, and EU cases have treated the regulation of political commentary on the Internet. As political blogging grows in popularity, the reach of these sites, and their influence in political campaigns, may make them a target for regulation by rivals and incumbents, both at home and abroad. Since ordinarily any URL can be reached from anywhere with Internet access, conflicting domestic rules about what can be said (and who can say it) present potential for conflicting rules on blogging.
