This is a great question!
I find George Washington, not Abraham Lincoln, to be our greatest president. I would rank Abraham Lincoln a close second, though. I find George Washington to be our best president because he fought for SO many years as our general (and did a great job overall) and then was able to get the members of the constitutional committee to come together, although there were many disagreements and at times, hard feelings. Finally, he had the daunting task of being the very first president of a brand new country and no one else could have been in that position except Washington. He was the only leader who could tackle that position.
