When one studies the Presidency, it always comes down to one issue that can undermine their historical reputation.
So for John Adams, for example, it is the passage and enforcement of the Alien and Sedition Acts of 1798.
For James Madison, it is the burning of the White House and Capitol Hill in 1814 by the British during the War of 1812.
For Andrew Jackson, it is the forced removal of five Indian tribes to Oklahoma in the 1830s, the so called “Trail of Tears”.
For Franklin Pierce, it is the signing of the Kansas Nebraska Act in 1854, bringing the nation closer to the Civil War of the future.
For Woodrow Wilson, it is the violation of civil liberties during the First World War, and immediately after, during the Red Scare of 1919-1920.
For Franklin D. Roosevelt, it is the internment of Japanese Americans during World War II.
For Lyndon B. Johnson, it is the escalation of the Vietnam War in the mid 1960s.
For Richard Nixon, it is the engagement in the Watergate Scandal in the early 1970s.
For George W. Bush, it is the provoking of the Iraq War in 2003 and after.
And for Donald Trump, it is the collusion with the Russian government Vladimir Putin, which is going to bring down his Presidency.
