Of all the terrible things the government has done in the past 1 / 10 / 100 years, I don't think that a candidate coordinating with Russia about which fake news to publish is even worth mentioning.
If Congress has the guts to investigate the Steele dossier (which alleged Trump traded eased regulations for oil interests) then that's great. And if he is impeached on that basis, that's great too, although it leaves us with a probably worse Mike Pence. Better yet is if the entire government falls.
I'm not defending Trump or his conduct; I'm just saying this is a distraction.
