 Mr. Trump has shown a character unworthy of the responsibility of the presidency. He has demonstrated an utter lack of respect for the Constitution, the rule of law, and the American people. Instead of a cogent vision for the country's future, Mr. Trump is animated by a thirst for political power. To use the levers of government to advance his interests, satisfy his impulses, and exact retribution against those who he thinks have wronged him. He is, quite simply, unfit to lead.
