Modern politics, especially the "power heavy" end, is loaded with misfits. That system runs on blackmail, quid pro quo, and payoffs. It is not amateur at all to dig up the dirt, and use it.
Yeah I guess they have to do the whole “digging for skeletons” thing as a matter of course. But they should know it won’t work as a strategy. Anyway for Hillary to accuse someone else of wrongdoing of any kind is just too rich.
