1. It's funny/odd that this has come up so many times in history and never been challenged or resolved in those instances.
2. Based on the universal principles which inspired the Declaration of Independence (which the Founders obviously did not live up to) everyone should be able to be President regardless of place of birth.
3. It's funny as hell, just in a historical sense, to look at this upcoming general election and think of Obama as more American than John McCain, especially as defined by the Framers.
