Last week, the American Conservative Union held its annual conference (CPAC) in Washington, D.C., offering three days of speeches from Conservative pundits, Members of Congress, and, of course, the GOP Presidential Hopefuls (minus Ron Paul). CPAC organizers are staunch supporters of free markets with leanings toward open-border policies and a more generous guest worker program. But the more than 10,000 attendees at this year's annual conference showed a preference for lower legal immigration levels and tough immigration enforcement.
