Biden, Trump rally troops on eve of crucial midterms

Joe Biden and Donald Trump headline a frantic last day of campaigning Monday on the eve of a midterm election that will shape the rest of the US president's term -- and could pave the way for a White House comeback by his predecessor.

After months of divisive campaigning, Biden and Democrats face a gargantuan struggle to hang on to Congress, in a race that he has cast as a "defining" moment for American democracy -- though kitchen-table issues like inflation have largely dominated voters' minds.
