Let's just keep things real here.
This report was never going to make anything happen that isn't already happening, and the reason why is obvious. Because if the people that could go after Trump actually wanted to go after Trump, they could have by now for any number of reasons. I have literally lost count of the number of things that he has said and done that, on almost any other politician, would have been a resounding death knell.
The people that support Trump in Congress want to have their way so badly that they literally sold their souls to make it happen. And I haven't heard any of them apologize yet. And the voters that support them are so busy feeling the same way that they won't accept truth when it's slapping them in the face. So the Mueller report could have literally had a photo of Trump kissing Putin's nuts, and there would still be 30-some odd percent of the GOP base willing to ignore that, and another 30 or so percent that don't like it, but hate abortion more. And as long as that is the case, the GOP won't move a muscle.
People keep waiting for Republicans to grow a spine and feel like things have "gone too far", but keep in mind that Trump spent the past week literally dragging a dead man in public, a supposed friend and colleague of theirs, a damn Republican even, and these bitchmade would-be representatives sat on their hands.
So, yeah, this report will probably have some telling information in it. And hopefully, it bears out into some kind of productive investigations and actions in the future. But we're still back to "vote these assholes out in 2020", which is honestly becoming a more and more practical solution with each passing day. You know, so long as Dems don't sit on their own balls while trying to pat themselves on the back.
TL;DR Repubs stay Repubbing. Don't expect them to move, so their supporters won't move, either. And vice versa.
