During a speech designed to counter notions that the economy is still struggling seven years after the Great Recession, Obama suggested Republicans were painting an overly gloomy picture.
"There is nothing particularly patriotic or American about talking down America," Obama said in barbed remarks that also featured a direct swipe at Donald Trump -- who has campaigned to "make America great again."
"Despite the perennial doom and gloom that I guess is inevitably part of a presidential campaign, America is winning right now. America is great right now," he said sharply.
"You wouldn't know of this if you were listening to the folks who are seeking this office that I occupy."

Long-term unemployment rates remain high and workers' earnings have not substantially rebounded, meaning tough times remain for many middle class Americans and the working poor.
