I’m not going to bother spending too much time on this. The Mueller report is finally public (well, most of it, anyway). But does it change anything? Trump’s supporters will insist that Mueller’s decision not to charge Trump means Trump did absolutely nothing wrong (even though that decision was made at the outset of the investigation). Trump’s opponents just have more evidence and details for what’s already been established.
In principle, the report could be used as the basis of impeachment. Indeed, Mueller makes it quite clear that it’s intended to be the basis of an impeachment. Unfortunately, Republicans don’t want to impeach Trump, and there are maybe five Democrats who would be willing to make Republicans either join the impeachment train or reveal themselves as being that unwilling to hold Donald Trump accountable, so it’s not going to happen, especially since Nancy Pelosi isn’t one of the five. As in too many other situations, mainstream Democrats are more concerned with some amorphous qualification of “electability” than with actually doing anything to make it worth electing them. (Republicans could be subject to their own criticism, of course, but what would be the point? Democrats at least have a chance, however slim, of changing.)
