Michelle Fleury and Ben Crighton travel from Louisville in Kentucky to New York on the East Coast. Along the way they speak to miners, environmentalists, food bank volunteers, drug addicts and former school students about President Obama’s legacy. Although the economy seems to have recovered from the global financial crisis, they encounter anger and disillusionment, and find that much of the optimism that swept Obama into office in 2008 has been replaced by division in Washington and across the country.In the weeks before the 2008 US election, the BBC drove a bus coast to coast across the US asking people about their lives and their hopes and fears for the future. In the four-part series America Revisited we meet some of those same people again to find out why the country seems more divided than ever.Picture: Billy and Doug are retired miners who are worried about their pensions, Credit: BBC
