 Well, yes and no. I mean, typically when you've got an incumbent, there isn't a primary. There's the pretense of a primary, which is a system to basically reaffirm your candidate and get them on the ballot. The last time that there was a seriously contested primary in either party, to the best of my recollection, was 1980 when Ted Kennedy took on Jimmy Carter, which hurt Jimmy Carter terribly, by the way.
