(AP) - Democrats hold 58 of the seats in the state House, while Republicans hold 52. All of them are up for grabs in the November election. Here are a few of the more interesting races to watch:
1st District: Republican Mary Treder Lang, an accountant, and Democrat Timothy Bledsoe, a Wayne State University political science professor, square off for this open Wayne County seat. Moderate Republican Ed Gaffney of Grosse Pointe Farms is giving up the seat because of term limits. Both candidates survived tough primaries against several opponents.
17th District: Democratic House Speaker Andy Dillon of Wayne County's Redford Township faces a strange Election Day. He's challenged by underdog Republican Sandra Eggers in the general election and he also faces a recall vote over his decision to support last year's tax increases in Michigan. Eggers has been active in the recall effort.
20th District: Democrat Marc Corriveau of Northville surprised many when he won this seat in 2006. He'll try to hold on against Plymouth Republican Jerry Vorva, a former state representative.
24th: Republican Jack Brandenburg of Macomb County's Harrison Township leaves this potential swing seat because of term limits. His son, Byran Brandenburg, is the GOP nominee. Macomb County commissioner Sarah Roberts will try to claim the seat for Democrats.
37th District: Democrat Aldo Vagnozzi of Farmington Hills leaves the seat because of term limits. Democrat Vicki Barnett, a former Farmington Hills mayor, and Republican Paul Welday, a businessman and former chief of staff for U.S. Rep. Joe Knollenberg, are trying to replace him.
39th District: Republican incumbent David Law could have run for re-election, but he wants to be the Oakland County prosecutor. Democrat Lisa Brown, a real estate agent with a law degree, and Republican Amy Peterman, a former Walled Lake School Board president, are competing to replace him.
65th District: Democrat Mike Simpson beat an incumbent Republican to win this Jackson County seat in 2006. He's since been a target for the GOP, which is running Blackman Township Supervisor Ray Snell against him.
75th District: Incumbent Democrat Robert Dean was targeted for recall until anti-tax advocates shifted their attention elsewhere. He's being challenged by Republican business owner Dan Tietema for this seat representing part of Grand Rapids.
91st District: Democratic incumbent Mary Valentine is being challenged by Holly Hughes, a member of the Republican National Committee, for this Muskegon area seat. Valentine was one of three Democrats to beat a Republican incumbent in 2006.
101st District: Democrat Dan Scripps faces Republican Ray Franz, who survived a tough primary, for a seat representing four northern Michigan counties. The seat is open because incumbent Republican David Palsrok of Manistee is leaving because of term limits. Scripps narrowly lost to Palsrok in 2006.
108th District: Incumbent Republican Tom Casperson of Escabana can't run for re-election because of term limits so he's running for the U.S. House. His replacement in the Upper Peninsula district will be either Republican Mike Falcon, a Northern Michigan University administrator, or Democrat Judy Nerat, a Menominee County road commissioner.
