Josh Wingrove | (TNS) Bloomberg News President Joe Biden’s campaign already sees one victory from the upcoming debate with Donald Trump — the absence of third-party challenger Robert F. Kennedy Jr. from the stage. Kennedy and other independent presidential contenders failed to meet the criteria to qualify for Thursday’s debate in Atlanta, according to host CNN, boosting Biden’s efforts to cast the 2024 race as a two-person contest between him and Trump. The showdown comes as Biden looks to shore up the broad electoral coalition he’ll need to defeat Trump and his fervent conservative base.
