Ferraro is now so long ago that I'm not sure that'll be much of an issue. Our national political attention span isn't that long.
You're right, Ferraro is ancient history as the younger voters in 2008 of ages 18-24 will have been born in Reagan's second term, thus not even been born during the 1984 election (or no more than 1 year old). Heck, even the 18-20 year olds in 2008 weren't even born during the 1988 campaign (or no more than 1 year old) and thus have only known a Bush or Clinton in the White House. So, we'll have a great number of voters born in the late 1980s and even 1990.
Having said that, given that younger voters are more generally Democrat than Republican, then the electoral slaughter of Mondale and Ferraro will not even be considered. Its like me (born in 1982) and Jimmy Carter's administration or the attempted Reagan assassination in 1981.
