Speculation arises around the potential fallout of a Joe Biden withdrawal from the presidential race, with no historical precedent for a major party nominee dropping out during the general election campaign. Instances of parties changing candidates at the statewide level have occurred, such as in New Jersey in 2002 when Sen. Robert Torricelli faced an ethics investigation. Meanwhile, as the Democratic National Convention approaches, internal divisions among Democrats intensify, with concerns over Biden's candidacy. On the Republican side, speculation mounts about Donald Trump's choice for a running mate, with figures like Sen. Tim Scott, Sen. Marco Rubio, and Sen. J.D. Vance being considered, though Vance's beard may pose a unique challenge due to Trump's aversion to facial hair.
