It is truly wondrous and arresting to see the Constitution in action, to see its ultimate tool — impeachment — employed, to see this mechanism that the drafters of the document must have considered an 11th-hour alternative be called up out of necessity.
It is not a thing to be celebrated. It is a thing to be soberly considered. It is a sign that the character and behavior of the target — in this case the president — are being searched for deficiency (in this case already demonstrated) and that the American electorate has been betrayed.
Still, it is awe-inspiring and reaffirming to see politicians put what is right above that which might be risky, to stand on principal in an area consumed by political expediency.
