I disagree. If he fails to pay the debt even though he has 8 or 10 times the revenue necessary, thus causing great harm to America and Americans, then he should be impeached. Boehner, if he had any gumption, would be on the Hill saying that he would personally file the Articles of Impeachment if Obama tried that. Impeachment is for high crimes and misdemeanors. Misdemeanors means “bad behavior” in Constitutional law. I think intentionally destroying the American economy in order to punish Americans for not wanting to be socialist qualifies.
What if the interest payment make up 100% revenue, is defaulting still an impeachable offense then? What you’re really saying is dereliction of duty is impeachable, not defaulting on the debt when its mathematically impossible to pay
