In 2000, Katherine Harris served as both the state's top election official and the head of the Bush-Cheney Campaign.

For 2004, in Michigan — a key swing state — Secretary of State Terri Lynn Land helps chair the Bush-Cheney Michigan Campaign.

Missouri is another key battleground. There, Secretary of State Matt Blunt is running for governor and actively campaigning for President Bush. He could be the one to referee both races if they're close.

Democrats play the same game. In West Virginia, Secretary of State Joe Manchin is running for governor.
