Just for yucks, I decided to see if this question can be answered in any kind of reasonable way. So I took this list at Wikipedia, which has a list of Presidents ranked from best to worst. The table in the cite lists 12 different surveys that have been done to sort out the best and worst presidents. I used the 1982 survey of historians, because I figured that A) it would be less partisan to discuss because these presidents are all dead, B) it would be more serious than a public poll, and C) because it’s no doubt biased to the left, so people can’t accuse me of cherry-picking conservatives.
And just so you know, I didn’t do this for other polls and pick the results that best suit the thesis - others are welcome to try.
What I did was list the top 10 and bottom 10 presidents, then see what their previous experience was to see if there was a correlation.
The top 10 Presidents:
- Abraham Lincoln
- Franklin D. Roosevelt
- George Washington
- Thomas Jefferson
- Theodore Roosevelt
- Woodrow Wilson
- Andrew Jackson
- Harry S. Truman
- John Adams
10 Lyndon B. Johnson
The bottom 10 (starting from the worst):
- Warren G. Harding
- Ulysses S Grant
- Richard Nixon
- James Buchanan
- Andrew Johnson
- Franklin Pierce
- Calvin Coolidge
- Millary Filmore
- John Tyler
- Zachary Taylor
Previous experience of the top 10:
- Lawyer, member of the house. No executive experience
- State Senate, Governor of NY, Secretary of Navy
- Commanding General, U.S. military
- Governor of Virginia, minister to France
- Governor of New York, Asst Secretary of the Navy
- Governor of New Jersey
- Senator, Military governor of Florida, Supreme Court Justice
- Senator, Vice President
- Lawyer, Ambassador, Vice President
- Senator, Vice President
So, in the top 10 we have three former Vice Presidents, five governors, one general, and one who didn’t have any executive experience.
Previous Experience of the bottom 10:
- Senator
- General
- Senator, Vice President
- Member of the House, Secretary of State
- Governor of Tennessee, Vice President
- Senator
- Governor, Vice President
- Member of the House, Vice President
- Senator
- General
So, three Senators, one congressmen, two Vice Presidents, two governors, and two generals.
Looks to me like there’s a pretty good correlation between experience as a Governor and good performance in office. But it may not be the ‘experience’ that matters, but the fact that being a governor is close enough to being a president in duties that people can tell if you suck at it or not. The bad governors don’t make it to the Presidency.
But this is a very small sample set, and one thing is clear that executive experience is no guarantee of good performance, and lack of it is no guarantee of bad performance. But if you’re a betting man and want to know the best stat to look at to determine if someone will make a good president or not, being a former governor is a pretty good one.
If someone else wants to try the same analysis using other poll data, or for all the rest of the presidents, be my guest. It looks like it would make for some interesting debate.
