"High crimes and misdemeanors", like "good behavior" for judges, was deliberately left vague by the Founding Fathers. They understood that no number of laws or procedures could define or prevent all cases of the calamitous abuse of power, so wrote in a political safeguard.
Exactly right and misdemeanor is defined loosely as poor judgement or any unacceptable behavior including incompetence. Obama easily qualifies for impeachment just on the Bergdahl case alone let alone his erasure of the southern border, Fast and Furious, unacceptably lavish vacations, Cash for Clunkers, Benghazi, IRS targeting. Iraq abandonment, - the list is incomprehensibly long - better play the race card ( which is impeachable too)
