re: #243 Interesting Times
Pro-impeachment people are making the argument that failure to impeach Barr makes it much easier for him to engage in voter suppression - so as I see it, impeachment helps rather than hinders b) on your list.
He can’t suppress any votes since he doesn’t run any state elections. They’re arguing that he can discredit them, which, while true, Trump doesn’t actually need Barr to make those arguments. He’s been making those since 2016.
