Most Americans don’t realize Robert Mueller’s investigation has uncovered crimes

...
One can interpret this pattern of behavior in a few ways. One is that Mueller is steadily putting in place the building blocks of a huge, mafia-style takedown that will end with Manafort “flipping” under pressure and new indictments coming against members of Donald Trump’s family and damning evidence about Trump himself. Another would be that when placed under a microscope by an aggressive prosecutor, several Trump aides turn out to have been involved in financial malfeasance only loosely related to the Trump campaign and Trump himself did nothing wrong. But there is definitely evidence of crimes — including some serious ones — by a range of figures, some Russian and some Americans and some working at a very high level in Trumpworld. 
Yet despite what most Americans perceive to be a very steady drumbeat of Trump-Russia news, the majority of the public is completely unaware of these critical facts. 
That suggests that the press as a whole has not done a good job of actually conveying factual information to our audience, that Democrats’ messaging on the investigation has not been clear enough on the most damning point (Trump, even if otherwise innocent, is guilty of hiring crooks and trying to prevent an investigation into their activity), and that Trump’s counterstrategy of muddying the waters around the investigation has been fairly successful.
