***UPDATED: COLUMBIA STOP PLANNED
A Democratic Party source tells the KY3 Political Notebook that Barack Obama and Joe Biden will campaign in the state Thursday.
The two will campaign separately, in different parts of the state. Obama will hold an event in Columbia at 9:30 p.m. It's unclear if a stop will include the Ozarks.
"Probably not," says the source.
