MILWAUKEE (AP) - A combative President Barack Obama has rolled out a long-term jobs program before a cheering Labor Day crowd and coupled it with a campaign-season assault on Republicans for causing Americans' hard economic times.
      
The program will exceed $50 billion to rebuild roads, railways and runways. But it's fate in Congress is in doubt.
      
GOP leaders instantly assailed Obama's proposal. And Democrats will likely be reluctant to approve additional spending and higher federal deficits just weeks before elections that will determine control of Congress.
      
Obama said Republican policies have led to record federal deficits and caused "the worst economic crisis since the Great Depression."
      
Republicans are making it clear that they won't be helping with the plan. Senate GOP leader Mitch McConnell says he has "justifiable skepticism." He says Americans are "still looking for the 'shovel-ready' jobs they were promised more than a year ago" in the original stimulus program.
