In your opinion what constitutes high crimes and misdemeanors?

I believe you are referring to two separate terms, high crimes, and misdemeanors. Misdemeanors are lower level crimes punishable by confinement in a county jail for a period of no longer than one year. High crimes are felonies (higher level crimes) punishable by confinement in a state or federal prison for a period of one year to life, or the death penalty.
