Nominee Mitt Romney "did not offer a single new idea," but "a retread of the same old policies that have been sticking it to the middle class for year," Obama told supporters at a rally near Des Moines, Iowa.
Obama, who accepts re-nomination from the Democrats next week at their convention in Charlotte, N.C., said Romney's proposed tax cuts would starve middle class programs like Medicare and education.
Voters are familiar with GOP plans because they applied them last decade, leading to the financial meltdown of 2008.
"You've lived through it," Obama said. "You can't afford to repeat it."
