Who did George H. W. Bush run against in 2000 and 2004 elections?

George H. W. Bush did not run in the 2000 and 2004 elections; it was his son, George W. Bush, who ran in those elections. In 2000, George W. Bush faced Democratic candidate Al Gore, and the election was notably decided by a very narrow margin following a controversial Supreme Court decision regarding Florida's votes. In 2004, he ran against Democratic candidate John Kerry and was re-elected.
