Democrats talking about impeaching President Trump are so absurdly premature as to convict themselves of extreme political hackery.

Their excuses for impeachment change with the news cycle, but right now, the only ground remotely reasonable for impeachment is the evidence reported by inspector general Robert Mueller that Trump tried on 10 occasions to impede the Russia-related investigation. The contrary arguments, though, are strong. The first two are that Trump apparently committed no underlying crime to cover up and that he provided remarkably free access to requested documents and to members of his team without asserting executive privilege. It’s hard to charge obstruction when he destroyed no documents and suborned no perjury.
