In a separate vote, the Senate approved new proposed boundaries for districts in the 38-member state Senate and the 110-member state House. The plans already have been approved by the Republican-led Michigan House.
Court challenges are possible as Democrats are opposed to the plans and say Republicans are trying to protect their own incumbents while possibly violating federal protections for minority voters.
Michigan is dropping to 14 congressional seats from 15 because of declining population.
Both Levin and Peters have said they plan to run for re-election, although neither has indicated he would run against the other. Peters could move within Oakland County and challenge one of two Republican incumbent congressmen, Mike Rogers of Howell or incumbent Thad McCotter of Livonia. But those districts lean Republican as redrawn under the proposed map.
Republican state Sen. Judy Emmons of Sheridan joined Democrats in opposing the congressional redistricting proposal.
Wayne County and the city of Detroit will lose clout under the plan because of lost population between 2000 and 2010. That loss in clout also is reflected in the maps proposed for the state House and state Senate, which passed the Senate by a 29-9 vote.
Although the state has until Nov. 1 to put the maps in place, Republican lawmakers wanted them passed this month to leave time for legal challenges from opponents. Democrats and citizen advocacy groups have argued unsuccessfully for giving the public more time to comment on the maps before they’re passed.
The congressional redistricting bill is House Bill 4780. The legislative redistricting bill is Senate Bill 498.
