Michigan's Democratic congressional delegation wants to replace the long-time chairman of the state Democratic Party.
Sens. Carl Levin, Debbie Stabenow and five members of the U.S. House wrote an open letter to Democrats Tuesday backing Lon Johnson over incumbent Mark Brewer.
Brewer has served as party chairman for 18 years and is hoping to be re-elected later this month.
But support from some heavy-hitters is growing for Johnson, who lost a state House election in northern Michigan in 2012. His wife was deputy campaign manager for President Barack Obama's re-election campaign.
Those in congress note that the GOP still controls all parts of government in MIchigan.
In a letter, Sen. Stabenow says, "We believe that the combination of challenges and opportunities that dramatically confront Michigan Democrats today have called on us as elected Democrats to urge a new and inclusive chapter in MDP leadership."
