Terry Branstad gets to appoint Harkin's successor to the United States Senate, and there is a 1994 United States Senate Special Election in Iowa, which is won by a Republican. Branstad would probably appoint either Tom Tauke or Jim Ross Lightfoot, and they go on to win election in their own right in 1994 and 1996. For a running mate in 2000, I think Harkin would nominate either Bob Graham (who delivers Florida to him) or Bill Bradley.
