Editor's note: This story has been changed to update the speaking time for Barack Obama Monday and the confirmation of the location of Mike Huckabee's appearance.

Presidential candidates from each major political party will be making visits to Roanoke on Monday.

Democratic candidate Barack Obama, a U.S. senator from Illinois, will speak at Jefferson Center in Roanoke on Monday morning at 7:30 a.m. Republican candidate Mike Huckabee, a former Arkansas governor, will hold a rally in Roanoke at 7:15 Monday night at the O. Winston Link Museum.

Tickets are required for the Obama event. The tickets are free and can be picked up at the Obama headquarters at 110 Kirk Ave. in downtown Roanoke after noon today. There is a limit of two tickets per person.

The Huckabee campaign confirmed Sunday that the location of the rally for Huckabee will the O. Winston Link Museum, 101 Shenandoah Ave. in downtown Roanoke.

Even though the Obama rally is early on a weekday morning, Trish White-Boyd, a Roanoke-area Obama organizer, said she expects a big turnout.

"That place ought to be packed," she said. "People are already calling."

Volunteers were asked repeatedly about Obama's visits as they canvassed neighborhoods and made phone calls Saturday, she added.

Chuck Sailors, the event organizer for a local grass-roots organization that supports Huckabee, said the candidate has a lot of contacts in the area, including pastor Bryan Smith of Roanoke's First Baptist Church on Third Street. Smith is from Arkansas.

"He is definitely a prime candidate for Virginia," Sailors said.

Even though Arizona Sen. John McCain has a firm lead in the nomination battle, Huckabee "is still in it," Sailors said.

Huckabee is also scheduled to speak at 11:55 a.m. today at Thomas Road Baptist Church in Lynchburg, according to his Web site.
