We are mayors. And, although we supported different Democratic candidates in the Pennsylvania primary, we are firmly united in our commitment to ensure that all the presidential candidates address a topic critical to the future of our state and our country: America's cities.
Cities are essential to our nation's well-being. And now, more than ever, as our nation heads toward a period of economic downturn, we must ensure that urban issues are not simply a domestic-policy issue for the candidates to debate, but the domestic-policy issue that frames solutions to our economic woes. After all, according to the Brookings Institution's Metropolitan Policy Program, the United States' 100 largest metro areas contain 65 percent of the nation's population and generate 75 percent of its Gross Domestic Product. The six largest metro areas in Pennsylvania, with 68 percent of the state's population, generate 80 percent of its economic output.
