Based on the shit he pulled in the '16 primaries, he got what he deserved as far as I am concerned.
I assume that's a reference to his false claim that Cruz had had affairs. Ugly. Cruz's April, 2016 claim that Stone had planned out Trump's campaign was also false, given that Stone had left Trump's campaign in August, 2015 (i.e. about a month, if that much, after Trump first announced).
I'm going to trust that the jury's verdict was based on the evidence and was correct. That said, prosecuting Stone seems VERY selective, given how many Hate-Trumper officials lied through their teeth in Congressional testimony with, so far, utter impunity.
