The Washington Examiner:
Obama's bus tour was aimed at the historically Democratic Rust Belt territory. Since the United Steelworkers, United Auto Workers and United Rubber Workers organized the steel, auto and rubber factories in Pittsburgh, Cleveland, Akron, Youngstown and Toledo, this has been prime Democratic territory.
Even in 1984, when Ronald Reagan was winning a 59 to 40 percent landslide, this Rust Belt -- 19 counties in northern and eastern Ohio and 14 counties in western Pennsylvania -- voted 52 to 47 percent for Walter Mondale. It was 12 points more Democratic than the national average.
If these 33 counties had been a single state, they would have cast 19 electoral votes for Mondale, more than doubling the 13 he won from his native Minnesota and the District of Columbia.
In the 1980s, the Rust Belt was still smarting from factory closings and heavy job losses in the recession of the late 1970s. Most of those lost union-wage jobs never came back, and angry laid-off factory workers and their families were unpersuaded by the Reagan campaign's claim that it was "morning in America."
In the years since, the economy of the Rust Belt has changed. The biggest employers in Cleveland and Pittsburgh these days are not steel mills but hospital complexes.
There has been considerable outmigration of young people, and from 1980 to 2010, the population of these 33 counties declined by 7 percent while the national population increased by 36 percent. If they were a single state, they would have 14 electoral votes, down from 19 three decades ago.
The aging electorate of the Rust Belt remains Democratic, and these counties voted 56 to 42 percent for Barack Obama. But that means that they were only 3 percent more Democratic than the national average.
The polling data suggest Obama is not running as strong in the Rust Belt counties this year. The bus tour was undoubtedly aimed at pushing his numbers up.
But he seems to have been left with little to say. No wonder he resorted to making jokes about his family and adding, "People've been commenting: I need to gain some weight."
As if to compensate, he ate some grits -- a staple once you get an hour of so south of Washington, but not so much up north.
But what else could he talk about? Certainly not the Environmental Protection Agency's rules shutting down coal-fired electric plants. Nor his decision blocking the Keystone XL oil pipeline.
He could hail the development of fracking in the region's Marcellus shale natural gas formation in the region, except for the fact that regulators in his administration seem intent on shutting it down.
He could repeat his calls for "investment" in education, but even if you don't regard that as a political payoff to the teachers unions, the dividends are going to be a long time coming in.
And calls for investment in infrastructure may lead people to recall his chuckling admission that there are no shovel-ready projects, thanks to regulatory and legal roadblocks.
The uncomfortable fact is that Obama doesn't have a convincing economic story to tell. The recovery summer promised for 2010 and for 2011 and again for 2012 has yet to arrive.
Obama needs majorities in the Rust Belt counties to carry Ohio and Pennsylvania again. But last week's bus tour shows he's having difficulty in this historically Democratic territory.
