Sixteen years ago, during the Republican primary campaign, John McCain went into South Carolina with a five-point lead over George W. Bush, having enjoyed a decisive victory in New Hampshire. A certain party with no official links to the Bush campaign organised a phone poll, asking: ‘Would you be more or less likely to vote for John McCain if you knew he had fathered an illegitimate black child?’ (McCain had taken his adopted daughter, who was born in Bangladesh, on the campaign trail.) It worked like a top for the Bush team. McCain lost the South Carolina primary by eleven points and never recovered. While the smear campaign was underway, during a break in a televised debate between the two candidates, Bush took McCain’s arm and assured him that he, Bush, would never countenance a dirty manoeuvre. ‘Don’t give me that shit,’ McCain told him. ‘And take your hands off me.’
