Biden and Trump look to debate to open up race currently in a dead heat

As the two prepare to debate on Thursday night, memories are revived of the ugly exchanges when they last squared off

It could be the moment when a rematch that few seem to want finally comes to life: like two ageing prizefighters, Joe Biden and Donald Trump will enter the arena of political bloodsport on Thursday evening to resume a verbal sparring bout that will revive memories of the ugly exchanges when the two debated face to face four years ago.

A CNN studio in Atlanta will host the first presidential debate of the campaign between the same two candidates who contested the last election, which Biden won.
