Presidential Greatness

While I spend a good deal of time wondering why certain presidents are considered failures, I'm also curious about those men we think of as the great presidents. To help me figure this out, I recently started reading Mark Landy and Sidney Milkis's Presidential Greatness. 

As their cover suggests, we have only seen five truly great presidents: George Washington, Thomas Jefferson, Andrew Jackson, Abraham Lincoln, and Franklin Delano Roosevelt. 

In the coming days and weeks, I plan to critique their criteria for these five men as THE greats. For now, though, I'd like to know if you agree with this list. Are these men great presidents? If not, why not? Are they forgetting presidents you consider great? If so, make the case for their inclusion.

Let me know what you think in the comments below. I'm fascinated by this concept, and I'm eager to hear your opinion.
