EDITOR'S NOTE: This version is for you political nerds listening (respect!). This double-length episode goes deep into the different simulations, at a state level, at an Electoral College level, and how the Constitution gets wrapped up in what could a full-blown legal battle.  If you want to skip all of that, go to the 'This Matters' feed and just listen to the condensed What if Trump won’t leave? version.  U.S. President Donald Trump has repeatedly cast doubt on whether he would accept the results of election day in November. What if Trump loses the election but refuses to leave the White House? Today on This Matters, Geoffrey Skelley, elections analyst for FiveThirtyEight, breaks down how Trump can dispute the results, why it could turn into an ugly fight at the Supreme Court level and what the legal checks and balances are to ensure the election winner serves as president.
