Couple of points here.
Yes, politically motivated is always what goes on in DC. That's pretty much a given.
Yes, the field agents investigate, report their finding up the chain of command to some middle layer which draws the conclusions and recommendation to the DOJ for prosecution or not. Given this, why is it Comey's job to do this publicly? Would seem that the more standard course would be to put his cover letter on the top, and forward it to the DOJ's federal prosecutors who would then make it public.
Given the field agent's reaction to Comey's public declaration at his press conference, large numbers of them involved in the case clearly believe prosecution was warranted.
Given this middle layer made the call and not Comey, if they did, it is this middle layer that also invented the 'lack of intent' excuse that let her off the hook. It is the middle layer that corrupted the results or at least the conclusion drawn from the investigation.
Hypocrisy in DC is only exceeded by the politics being played. The fact of the matter is that Comey was the federal prosecutor that let Hillary off the hook with the WhiteWater scandal, so calling him a Republican stooge is probably wrong. Perhaps calling him a Democrat stooge might be more accurate?
Agreed. No one in DC to trust as well as no one in the media to trust either. But I have to say, that after 8 months of no solid evidence of any Trump / Trump campaign and Russian collusion, no solid evidence, the entire meme stands on quicksand rather than something more solid. Leading Democrats are already backing away from it, with statements on the order of 'thy've never seen any evidence'. This includes Comey and Clapper, IIRC, stating the same. No, day by day as there's still no solid evidence it become less and less likely that there's anything there. Of course, some heavily invested in the meme just refuse and deny this outright. To them I say: "Bring some solid evidence, then I may reconsider. Until then, I'm not seeing it".
