from the general public's perception, it would seem the poll is about right. Most people still only hear what MSM tells them. For example,just heard today at work about what a destructive force the Qannon conspiracy is. I highly doubt the person espousing that viewpoint knew anything about it other than what MSM has told them. All the research in the world doesn't change what the public perceives, or what the DOJ actually does, so even as I generally support Trump, it seems 50/50 is about right for the reality of the country we live in at this point. Its not a question of who do you want in jail, it is a question of who is more likely to end up there.
