The Presidency is an all encompassing job, one that the occupant of the Oval Office, particularly in modern times, cannot escape, even when on so called “vacation”.
Some Presidents stand out as constantly on the job, very active, very committed and hard working.
These would include in modern times, since 1900, Theodore Roosevelt, Woodrow Wilson, Franklin D. Roosevelt, Harry Truman, John F. Kennedy, Lyndon B. Johnson, Richard Nixon, Jimmy Carter, George H. W. Bush, Bill Clinton, and Barack Obama. Note only three of these Presidents–TR, Nixon and the first Bush–are Republicans.
Indications are that James K. Polk and Abraham Lincoln, Democrat and Republican respectively, were also hard workers, dedicated, and committed, among pre1900 Presidents.
On the other hand, the following Presidents come across as far less committed, and in many cases, too laid back, and in some cases, purely lazy:
William Howard Taft, Warren G. Harding, Calvin Coolidge, Herbert Hoover, Dwight D. Eisenhower, Gerald Ford, Ronald Reagan, and George W. Bush, all Republicans. All of these Presidents took many vacations, and had short work days much of the time, and it undermined America in domestic and foreign policy on a regular basis.
Pre1900 examples would include Franklin Pierce, James Buchanan, and Ulysses S. Grant, the first two being Democrats and Grant being a Republican.
And then there is Donald Trump, whose work habits make clear that he is the LAZIEST President of the United States in all of American history, certainly since 1900 at the least!
He loves to sign executive orders, many which are symbolic, and to take a long time in signing in a flourishing manner at Presidential signing ceremonies, and then showing it to the gathered audience over and over, like a little child proud of his signature, absolutely unbelievable immaturity on the part of a President, who lowers the image of the Presidency every day.
He has taken no part in promoting Health Care legislation, and is simply ready to sign any bill that comes to his desk, as he told evangelist Pat Robertson in an interview before leaving for his trip to Paris, France for Bastille Day.
Trump knows no details on anything, and is not willing to do much reading or learning, and it is truly pitiful how he has degraded the Presidency daily!
