(CNN) -- President Barack Obama campaigned in America's car country on Monday after his administration filed a trade complaint against China's auto industry subsidies, while Republican challenger Mitt Romney complained the move was "too little, too late." Romney spoke Monday to the U.S. Hispanic Chamber of Commerce in his attempt to diminish the president's advantage with the Latino vote, a traditionally Democratic demographic that strongly supported Obama in 2008. With the November election just over seven weeks away, Obama seeks to maintain the momentum of a perceived "bounce" in support following this month's Democratic National Convention while Romney wants to gain ground on his rival ahead of the three presidential debates next month.
