MADISON (AP) -- Sen. Barack Obama will campaign in Wisconsin for the first time in two months this weekend.
His campaign says the Illinois senator will stop in the western city of Eau Claire on Sunday. The event is part of a tour of battleground states leading up to next week's Democratic National Convention.
The campaign did not offer details about the location or time of the event. It says Obama is expected to talk about how he will offer relief to struggling middle-class families.
The stop will be Obama's second in Wisconsin for the general election. His last stop was in Kaukauna in June.
Obama started the campaign with a healthy lead over Republican Sen. John McCain in Wisconsin, but the race seems to be tightening.
