With incumbent Governor John Engler ineligible to seek re-election for a fourth term, Posthumus, Michigan's lieutenant governor, was considered the overwhelming favorite for the Republican nomination. Following his primary win, Posthumus selected state Sen. Loren Bennett as his running mate. Jim Moody created a candidate committee and filed a Statement of Organization, but did not submit sufficient ballot-access petition signatures to be included on the 2002 primary ballot.
The Democratic Party was a competitive, three-way race with between state Attorney General Jennifer Granholm, former Gov. James Blanchard and former House Minority Whip David Bonior. Granholm was accused in the 2002 Democratic primary of several allegations of cronyism while working as Wayne County Corporation Counsel. Her husband, Daniel Mulhern, had received several contracts for his leadership training company shortly after Granholm left her position as a Wayne County Corporation Counsel in 1998. He received nearly $300,000 worth of contracts, despite being the highest bidder for one of those contracts. Opponents criticized Granholm supporters for engaging in cronyism and giving contracts to her husband immediately after leaving county employment. Granholm and her supporters responded that no ethical violations occurred and that Mulhern had earned the contracts on his own merits. Granholm was the first woman ever nominated by a major party to be Michigan governor. Following her primary victory, Granholm chose state Sen. John Cherry as her running mate.

The Michigan US Taxpayers' Party is affiliated with the United States Constitution Party, but Michigan election law does not provide a mechanism for changing the name of a political party.
General Election campaign
Posthumus, who had been previous Governor Engler's Lieutenant Governor, ran his general election campaign promising to maintain the Engler legacy. Granholm promised change, running as a tough crime-fighter and consumer advocate. Granholm criticized the Engler administration for coming into office with a budget surplus and leaving with a deficit.
Kilpatrick memo controversy
In the biggest event of the election, Posthumus released a memo from Detroit Mayor Kwame Kilpatrick asking for more appointments for blacks and jobs for Detroit contractors in a Granholm administration. Posthumus pointed to the memo as an example of Democratic Party corruption. Granholm, however, denied ever receiving the memo and said she wouldn't have agreed to it anyway. She said Posthumus was trying to be racially divisive.
