Jon Lieber, who leads Eurasia Group's coverage of political and policy developments in Washington, offers insights on US politics:

Is Trump out of options now that William Barr said the DOJ found no election interference?

Trump's problem isn't William Barr not finding election interference, it's that he lost the election and he lost it by millions of votes, and he lost it in the most important key states by tens of thousands of votes. Now, this was a very close election. The three closest states, Wisconsin, Georgia, and Arizona, Trump only lost by 44,000 votes so far, and if he'd ended up winning those three, we'd have an Electoral College tie. But the election was not close enough that Trump's strategy of trying to kick this to the courts and then getting it to go all the way to the Congress, with an alternate slate of electors, it just wasn't possible. Had the election been a little closer, he might've had a shot. But as it is, his chances are over. Joe Biden's going to be inaugurated on January 20th.
