A presidential election campaign approaches its climax as Barack Obama and Mitt Romney criss-cross the land in search of the last few votes. But my thoughts have turned to a couple of candidates of long ago, back in the news these past few days.
One is George McGovern, best known for his landslide defeat at the hands of Richard Nixon 40 years ago, who has died in his native South Dakota. The other is Robert Kennedy, indirect subject of a new documentary on the HBO channel devoted to his widow, Ethel, among the last living contemporary links to Camelot.
The programme was a reminder of what the country lost with the assassination of RFK, whose short-lived candidacy in 1968 remains one of the great "what ifs" of 20th century American history: how different things might have been if he had gone on to defeat Nixon at that year's election.
Just the names of Bobby Kennedy and George McGovern get you thinking: whatever happened to the old-fashioned American liberalism under whose banner they so proudly fought? Not today's diluted "liberalism" as practised by Obama which is little more than a schoolyard taunt hurled by right-wing talk-show hosts, but the liberalism that set out to right the wrongs of American society, first and foremost the scourge of poverty.
For Bobby, the reality of what he would call "the disgrace of the other America" struck home during his 1967 Poverty Tour of the Mississippi Delta. In McGovern's case, the concern was on a global scale after President John F Kennedy appointed him director of the Food for Peace programme in 1962.
