Texas Rep. Ron Paul is scheduled to attend a town hall meeting at the University of Maryland, College Park.
Paul, who is seeking the GOP's nomination to challenge President Barack Obama, is set to attend the event at Ritchie Coliseum on Wednesday evening.
Paul is in last place in delegates of the four candidates who are still in the race for the GOP nomination.
Maryland is drawing candidates this week, because the state's primary will be on April 3.
Former House Speaker Newt Gingrich was in Annapolis on Tuesday. Mitt Romney was in Arbutus last week.
