What it really boils down to is 7-9 years for talking trash to someone on a telephone. That's pretty absurd. People in this country don't get that sort of sentence for holding up a stop and rob with a loaded gun. Beyond that it's never been proven that he had any connection to Wikileaks or anything else, but how do you interfere with a Russian Collusion that didn't happen?
The sentencing for this entire situation is absolutely bonkers and politically driven.
Even if truly guilty on all counts, I'd still expect a 1-2 year sentence with supervision -- Stone would be a first time offender for a non-violent crime with possible reductions for cooperation and or good behavior in the future. If Trump commutes or pardons it'll be completely in regard to this, and I'd tend to agree even though I don't care much for Stone.
