It says in Article II, Section I, that
No person except a natural born citizen, or a citizen of the United States, at the time of the adoption of this Constitution, shall be eligible to the office of President; neither shall any person be eligible to that office who shall not have attained to the age of thirty five years, and been fourteen Years a resident within the United States.which means I won't be eligible to be the President until 2012, though that doesn't mean I can't run. What does it take to run president anyhow? Scholastic (Scholastic?) has a step-by-step guide. Here's a facinating article on what not to do in preparation for becoming president - don't be a sitting member of Congress. I think one should probably be governor first.
