The reality of impeachment is that there has to be a political will in doing so.
We already know that the will exist among 1/2 of the country who lean left.
Stories like this are designed to pick of enough percentage points, from those either against it, or on the fence, to get that mark over 50%.
Impeachment is political, and we know what constitutes "High Crimes", but ask the population to define "misdemeanors", especially as it would relate to someone in public office.
It could mean anything.
Jay walking is a misdemeanor, speeding, etc.
Frankly, you could claim all politicians commit "misdemeanors" every time they give a stump speech, by debasing their opponents and inflating there own achievements.
Of course, the first amendment covers free speech, but I think you can see where I am going with this.
