Biden to campaign in Missouri

WASHINGTON (AP) -- Democratic vice presidential nominee Joe Biden will campaign in Missouri on Tuesday.

The Delaware senator is slated to meet with voters to discuss the country's economic challenges.

Campaign officials have not indicated which city Biden will visit.

Democrats have targeted Missouri as a key state for winning the White House this fall. Presidential hopeful Barack Obama was in Kansas City last week on his way to the Democratic National Convention.

Biden will debate his GOP counterpart, Alaska Gov. Sarah Palin, at Washington University in St. Louis on Oct. 2.
