I think the best president in history was probably Abraham Lincoln, because he was president during the civil war.  He also helped to end slavery.   He was also a very good man.  I think that the hardest thing about being president would be being in charge of what bills become laws through the veto system.  Another hard part would be dealing with foreign countries and their problems.  I do not think that I would ever want to be president, because it can be a very stressful job.  I'm likely never going to run for president, so I don't have a campaign pitch.
