Joe Biden’s great-great-great-grandfather, Edward Blewitt, was overseer at the Ballina Union Workhouse in County Mayo from 1848 to 1850 during the Great Irish Famine. Many died in the workhouse and others perished in the temporary fever hospital built against one of its walls. With his family, Blewitt emigrated to Pennsylvania in 1851. He did well, despite the political power of the anti-Catholic, anti-Irish Know Nothing movement, a nationalist and Protestant political party, which in the 1850s had a hundred congressmen, eight state governors, and a controlling position in half-a-dozen state legislatures. Before his job at the workhouse, Blewitt had been an engineer for the Irish Ordnance Survey; in Pennsylvania he helped to lay out the new mining town of Scranton.

Trump was often derided as an isolationist by the imperial bureaucracy, for whom the term is a stock insult. His opponents liked to say he was tearing down the US-led ‘liberal international order’. In the Washington Post, Josh Rogin wrote that Biden held the promise of salvation from the Trump days: ‘a return to a bipartisan, internationalist foreign policy that moderate Republicans and Democrats have long championed’. In fact the Trump administration’s foreign policy was more orthodox than is generally admitted. Many of his appointees were old regime hands. Having pledged to ‘get out of foreign wars’, he did nothing of the sort. He pursued the global assassination programme established under Obama. The US-backed war in Yemen, begun while Biden was vice president, continued. The military budget increased.

This autumn was always going to be a tawdry season in America. The past couple of weeks have been a jubilee of below-the-belt viral content: a photograph of the former vice-president’s son leaning down apparently to snort powder off a woman’s bare buttock; a still from the new Borat movie of the former New York mayor in a hotel room with a young woman, leaning back on the bed with his hands in his pants; a story of a journalist pleasuring himself during a Zoom conference in the sight of his colleagues (he said he thought he’d turned the camera off). Sleaze and perversion are now the permanent backdrop of US politics. The world turns its eyes away from a hegemon whose henchmen can’t stop pulling their dicks out. By contrast, the final debate between Trump and Biden was almost decorous.

On the question of whether Donald Trump is a sinister mastermind or an incompetent scumbag (not mutually exclusive), last night’s debate will have to register in the scumbag column. His constant interruptions, vanity, self-pity and frequent forays into lies and nonsense are all by this point wearyingly familiar. Of course, Trump has been consistently underestimated since he entered politics, and his supporters no doubt enjoyed the petulant way he dominated proceedings. But his abuse of Biden was a far cry from the humiliations to which he subjected his opponents in the 2016 GOP primary debates. The show has gotten old.

When asked by Jim Lehrer, the host of Newshour on PBS, if Hosni Mubarak was a dictator, the US vice president, Joseph Biden, said: ‘Mubarak has been an ally of ours in a number of things and he's been very responsible on, relative to geopolitical interests in the region, Middle East peace efforts, the actions Egypt has taken relative to normalising the relationship with Israel... I would not refer to him as a dictator.’ Here are some excerpts from the rest of Lehrer’s interview with Biden, containing more of the VP’s candid assessments.
