This combination of photos taken in Columbia, S.C. shows former President Donald Trump, left, on Feb. 24, 2024, and President Joe Biden on Jan. 27, 2024. The clash between Biden and Trump on Thursday, June 27, may be the most consequential presidential debate in decades. Biden is desperately seeking momentum amid pervasive concerns about his age and leadership on key foreign and domestic policies. Trump will step onto the stage brimming with confidence, despite his status as the only presidential debate participant ever convicted of a felony. (AP Photo)
