(FILES)(COMBO) This combination of file pictures created on September 29, 2020 shows US President Donald Trump (L) and Democratic Presidential candidate former Vice President Joe Biden squaring off during the first presidential debate at the Case Western Reserve University and Cleveland Clinic in Cleveland, Ohio on September 29, 2020. - Two weeks before the polls, the contrast in campaign strategies between Trump, 74, and Biden, 77, has never been more pronounced: the Republican president led another rally in the battleground state of Pennsylvania October 20, 2020, while Democrat Biden stayed mostly out of sight ahead of a pivotal televised debate on October 22, 2020. Both candidates will get something of a reality check on Thursday when they meet for their second and final televised debate. (Photos by JIM WATSON and SAUL LOEB / AFP)
