"With back-to-back Republican and Democratic National Conventions, it's natural to focus on our differences," but "I am heartened to see the bipartisan support that exists for U.S. leadership in the world -- particularly for our global development efforts," Dan Glickman, former secretary of agriculture and chair of the Board of the Center for U.S. Global Leadership, writes in a Politico opinion piece. "Through programs like the President's Emergency Plan for AIDS Relief and the Global Fund to Fight AIDS, Tuberculosis and Malaria, initiatives started [during the administration of] President George W. Bush, nearly four million lives around the world have been saved," he continues, noting, "President Barack Obama has continued to champion and support global development efforts like PEPFAR and the Millennium Challenge Corporation, which demand results and ensure accountability for U.S. taxpayers."
