DETROIT (AP) -- For the first time in a decade, the longtime leader of the Michigan Democrats is at risk of losing his job.
Mark Brewer is up for re-election when Democrats meet Saturday in Detroit.
Brewer's counterpart, Michigan Republican Party Chairman Bobby Schostak, also is running for re-election Saturday when the state GOP gets together in Lansing.
Schostak is expected to survive a challenge by co-chair candidates Todd Courser and Cindy Gamrat, but Brewer's situation is a different matter.
The longest-serving state Democratic Party chairman in the country faces a stiff challenge from Lon Johnson, vice president of a private equity firm and a veteran of national political campaigns.
Johnson and his supporters are frustrated that presidential and U.S. Senate candidates win Michigan easily, but Republicans control much of the state government.
