Why should it be? Negotiations are always about Quid Quo Pro, are they not? You give this, I'll give that in return? How can you have negotiations between nations without it? So, if it were a crime, why didn't they impeach Obama when he promised he'd be able to deal with Russia better after the next election than before? i.e. if the Russians would wait he'd appease them. That is Quid Quo Pro isn't it? Bidden strong arming the former Ukrainian administration to fire a prosecutor or they wouldn't get the billion + in US aid was obviously Quid Quo Pro. Whether or not it involved his son is never here nor there. He wanted a 'favor' from them in exchange for them getting the money. Simple, right? Was he impeached? Of course not, because, while it was a dirty act of abused power, it was not impeachable.
