I'm not ignoring you, though I may soon begin doing so if you remain unresponsive. As I have already replied to you several times, Mueller's report states, repeatedly and explicitly, that the evidence does not establish that there was any "coordination between the Russian government and individuals associated with the campaign of President Donald Trump."
Mueller did not find collusion because there was no collusion and thus he charged exactly no one with collusion. Whether that is unsuccessful depends on your point of view, but he did successfully come to the proper conclusion that the evidence simply did not hold up the collusion claims. It was certainly wasteful though, because the flimsiness of the collusion theory was clear from the beginning. It's why the Trumptards have been so relaxed and jocular with their "This is it!" type responses for so long. Because a quick perusal of the evidence makes it obvious that the collusion theory was, as Van Jones described it years back, "a nothingburger".
