(CNN) - When President Barack Obama heads to Wisconsin on Labor Day to talk about the economy, one of the top Democrat's in the state won't be teaming up with the president.
Obama is scheduled to talk to working families and union members at Milwaukee's annual Laborfest Monday afternoon. While Sen. Russ Feingold will make a stop at Laborfest in the morning, he'll be gone by the time Obama arrives.
According to his campaign, Feingold will be at events in his hometown of Janesville and in Kenosha during the afternoon, when the president is in Milwaukee. The campaign tells CNN their schedule was set before the White House on Monday announced the president's Labor Day visit.
The three-term Feingold faces a very tough re-election against businessman Russ Johnson, the presumptive Republican nominee. Two of the top political handicappers, the non-partisan Cook and Rothenberg political reports, rate the race as a "toss up."
When the president was in Wisconsin last month, Feingold spent the day with him.
"I will stand with the president of the United States anywhere, anytime, no hesitation. I'm proud of what this president has tried to do," Feingold told the Milwaukee Journal Sentinel in an interview last month prior to Obama's visit.
A University of Wisconsin Badger poll of state residents conducted early this summer indicated that Obama's approval rating as president stood at 49 percent, with 46 percent disapproving of his job in the White House.
