Here are some events to keep an eye on as we head into the weekend. Tomorrow three presidential candidates will deliver commencement addresses around the country: Rudy Giuliani will address the Citadel Military College's Corps of Cadets in Charleston, South Carolina. Mitt Romney will head to Pat Robertson's Regent University in Virginia Beach, Virginia. And Hillary Clinton will speak to Wilberforce University's newest graduates in Ohio.

Also, Bill Richardson and Mike Huckabee will be attending events in New Hampshire while Joe Biden begins a three-day swing through Iowa with town hall meetings.
