US President Joe Biden’s not just dealing with concerns about last week’s presidential debate within the Democratic Party… A new poll by US television network CBS and YouGov reckons 72% of the country’s registered voters do not believe 81yo Biden is mentally/physically fit enough to serve another 4 years in the White House. That’s higher than polls conducted before Thursday’s debate, where Biden at times struggled to form full sentences. He’s fended off calls to allow someone else to take over the Democratic presidential candidacy ahead of the 5 November election. And his family is standing by him… Meanwhile, Biden’s political rival Donald Trump is claiming another win overnight, with the US Supreme Court ruling that presidents have immunity from prosecution for “official acts” carried out while in office – dragging his federal election interference case out further.
