You have to consider the much debated right of the vice-president to assume the presidency at that time as a national crisis. Tyler firmly established that right of ascension and stuck with his sense of what was right at that time. He alienated many, including his own party, at that time, but he has earned my respect for making a significant impact on the legitimacy of the office of the Vice-President.

President Tyler's greatest crisis as President was ensuring a smooth transition of power after the death of President Harrison. In this, he was indeed successful. He ordered himself to be sworn in immediately, thus setting a precedent that would pave the way for future orderly transfers of power after the deaths of Presidents Taylor, Lincoln, McKinley, Franklin Roosevelt, and Kennedy. With Harrison being the first President of the United States to die in office, it was quite natural that widespread uncertainty and fear erupted throughout the country. Tyler responded to this uncertainty quite well by ensuring a smooth transition of power. For this, he must be commended. Even though he failed to get anything done due to his stubborness and his mutual loathing for the Congress, Tyler still responded to Harrison's death exceptionally well and kept the nation moving in a time of great crisis.
