Who was the President during Day 1?
This has never been established for definite, but spin-offs have strongly implied that the President during the first season was Harry Barnes, a Republican whom David Palmer subsequently defeated in the election. Supposedly the first season was written under the silent assumption that Bill Clinton was the incumbent President, presumably meaning the creators intended for Day 1 to be in mid-2000 , though this has since been invalidated and Day 1 established to have taken place in 2004.
