No one can rouse Democrats better than Clinton, but even he'll have a very hard time making the case for the president in this ever- weakening and now fast shrinking economy. Especially since the former president has been, from time to time, one of Obama's critics over the past four years.

When Obama and his hired guns were doing everything they could to demonize Mitt Romney's successful career as a venture capital investor in job-creating businesses, Clinton spoke up for Romney's record at Bain Capital and called him "a sterling" example of a good businessman.

"I don't think we ought to get into the position where we say 'this is bad work.' This is good work," he said last May, adding that Romney's record as a governor and businessman "crosses the qualification threshold."

Clinton is also going to have to go before Democrats and defend Obama's specious argument that the Bush tax policies got us "into the mess we're in," so why go back to those tax-cutting policies now?

That's going to require a little dishonesty. While Clinton raised the top income tax rate to over 40 percent, he also cut taxes on upper incomes Americans in his second term, signing a Republican bill that reduced the capital gains tax on investors.

The Clinton economy was doing just sort of okay in his first term, but it went into overdrive after the capital gains tax cut, triggering a wave of new investment in the high tech sector that created millions of jobs and (contrary to what Obama Democrats believe) boosted tax revenues that led to a budget surplus.

Clinton, of course, won't remind convention Democrats of any of this in his speech, and the network news people won't mention it either. But keep in mind what Clinton said in June in a CNBC interview as you listen to his political spin from the podium. That's when he was asked about raising the two top income tax rates as Obama proposes at a time when the economy was weakening further.

"What we need now is to... avoid doing anything that would contract the economy," Clinton said. Asked if that meant extending all of the Bush tax cuts at the end of the year, even for those in the top income brackets, he replied, "They will...have to put off everything until early next year."

If timing is everything in politics, this may be the worst week Democrats could have chosen to officially kick off their general election campaign. A string of bad economic reports are coming out that will only remind the voters of Obama's failed economic stewardship.

Last week, there was Fed Chairman Ben Bernanke's blistering appraisal of the damage the high unemployment rate has inflicted "on our economy that could last for many years."

Then, on Monday, after Obama told a Labor Day crowd that the auto industry "has come roaring back", new data showed Tuesday that manufacturing continued its decline for the third straight month, as new orders, production and employment fell in August. Construction fell 0.9 percent in July, too.

Then, as convention Democrats return home at week's end, the jobless numbers will come out on Friday and are expected to be weak.

Obama's long-waited report cards are coming out, too. The Washington Post's respected economics writer Robert J. Samuelson writes that "Obama's economic report card is at best mediocre."

Indeed, after allowing him a pass on the first six months of his presidency, he gives Obama a grade of C- or D for his overall performance.

He's being too generous. This is the weakest recovery since the Great Depression and its getting weaker. I give him an F.
