Mark Sanford: Ron Paul's Heir?

Reihan has a challenging post on an AmCon essay on the paleo-libertarian from South Carolina:

He also deviates from the Republican line on foreign policy. In Congress, he opposed Clinton's intervention in Kosovo. And he was one of only two Republicans to vote against the 1998 resolution to make regime change in Iraq the official policy of the United States. He says that it was a "protest vote" in which he tried to reassert the legislature's war-declaring powers. When asked about the invasion of Iraq, he extends his critique beyond the constitutional niceties. "I don't believe in preemptive war," he says flatly. "For us to hold the moral high ground in the world, our default position must be defensive."
