I go by what the Constitution says, not Gerald Ford: high crimes and misdemeanors (low crimes). But is HAS to be a particularized crime.
I go by Constitution as well, but the DEMS pick and choose definitions and rules they will go by.
The phase actually means high crimes AND high misdemeanors. The high misdemeanors demonstrate intent associated with the high crimes (such as covering up, destroying evidence, hiding evidence, intimidating witnesses, etc.)
