'Atlantic' writer Barton Gellman returns to discuss what this election has revealed about our system's strengths and weaknesses, and what he's learned about the legal strategies the Trump and Biden campaigns are considering if the election is contested. Trump claimed victory on Election Night, and said he'd petition the Supreme Court to halt the vote counting. Gellman's latest articles are titled "The Election That Could Break America," and "How Trump Could Attempt a Coup." (Note: This interview was recorded on the morning of Nov. 4)
