You're absolutely right (unfortunately)
Most people don't care at all about the 'Russia Thing'. It's too damn complicated.
Most people don't watch MSNBC, or CNN, or fox news. All they know is that there is something being investigated about Russians and our elections. Most people don't know that the investigation has already resulted in indictments and guilty pleas. If they do know that, they don't really know who was indicted, or plead guilty to whatever. It's just a bunch of legal mumbo-jumbo nonsense.
It's kind of like the Whitewater thing with Clinton....most people didn't give a damn about it, until they heard about Monica Lewinsky, and her blue dress. Then, it got simple, and easy to understand.
In my opinion, anyone that is pinning their hopes on Mueller's investigation ending trump's "presidency' is going to be very disappointed.
I think that unless the orange clown has a stroke or heart attack before 2020 the only way we're going to be rid of him is to vote him out.....and that's not going to be near as easy as it should be.
