Cross-posted at The Western Right, Right Michigan, and Red Racing Horses.

All 38 seats in the Michigan Senate are up for election in 2014. Republicans currently have a 26-12 supermajority, and have controlled the senate since 1983.

Republican control of the state senate has prevented democrats from complete control of Michigan’s government, and stopped a lot of bad things from being passed. More recently, the Republican supermajority has prevented some of Governor Snyder’s more liberal plans from being implemented.

Fortunately for Republicans, the Michigan state senate is up only in midterms, which favor Republicans much more than presidential years. 2010 was very good to the Michigan GOP. Republicans picked up four state senate seats (and one earlier in a 2009 special election).

Republicans had complete control of redistricting this cycle. They crafted a very effective map. One democrat district was eliminated in Wayne County and replaced by a Republican one in west Michigan. Four other dem districts were made more dem. Most of the potentially vulnerable Republican seats were made more Republican, though a couple got slightly worse due to the need to avoid splitting counties. The new map is actually cleaner than the old one, excluding the Detroit districts, which are ugly for VRA reasons.

Michigan Redistricting: Official Republican State Senate Map Released
Michigan Redistricting: Republican State Senate Map Passed

There are ten open seats. Seven senators, four republicans and three democrats, are term-limited. Two republicans are just retiring, and one is running for Congress. Three Republican-held open seats (17, 20, 32) are tossups, and one other (13) could be competitive. Democrats have only one top challenger to a Republican incumbent (7), though another (34) could be competitive. Notably, dems failed to recruit credible candidates in several districts that were hotly contested in 2010 (29, 31, 38).

All but one of the current state senators are former state representatives. This pattern held in the past, and most credible candidates this time are current or former state reps.

I have included election data for the 2010 result in the corresponding (old) senate district, and 2008 McCain number and 2006 average (Governor, AG, SOS) for the new districts pulled from Dave’s Redistricting App. My analyses of how much redistricting changed the districts comes from comparing the old and new districts using these elections. More data is available from Republican Michigander’s district profiles.

Republican Michigander district profiles (see sidebar)

The McCain numbers look terrible for Republicans because he collapsed after publicly pulling out of Michigan. The largest McCain percentage in any Michigan state senate district won by a democrat in the past decade is 46.2% in (old) district 31.

Incumbent: Randy Richardville (term-limited)
Democrat: Doug Spade
Republican: Dale Zorn

Democrat: Sean McCann
Libertarian: Lorence Wenke
Analysis: Tonya won 58-42% in 2010 over Kalamazoo Mayor Bobby Hopewell. (The result was 53-48 in 2006.) Hopewell was a last-minute replacement for State rep. Robert Jones, who died shortly before the election. Tonya is from Van Buren county. Due to increases in population, Kalamazoo County became large enough to be its own senate seat, and the portion of Van Buren was lost. This moved the district to the left by 0.3/0.2%. Tonya will run in the new 26th district. Kalamazoo County is a battleground, with democrats usually winning the top of the ticket, and Republicans doing better at the bottom. O’Brien is a state rep from Portage (2010-2014). Lorence Wenke (Comstock, 2004-2010) is a free-spending but unpopular former state rep. McCann is a state rep (2010-2014 from Kalamazoo.

Old SS 2010: 36-64, McCain: 31.4, 2006 R Avg: 44.8 Romney: 34.2
Incumbent: Gretchen Whitmer (term-limited)
Democrat: Curtis Hertel Jr., Harold Leeman, Larry Hutchinson
Republican: Craig Whitehead
Analysis: Whitmer is the senate democrat leader. She is one of the few bright spots on the Michigan dems weak bench. She has ruled out a race for governor, but not for some other office. Hertel, the Ingham Register of Deeds, is the favorite here.

Republican: Rick Jones (incumbent)
Democrat: Dawn Levey
Analysis: This district drops Allegan and Barry and adds Clinton, Shiawassee, and NE Ingham, moving 4.2/4.1% left. It is safe for Jones, but could be competitive if open.

Democrat: Terry Brown
Analysis: This district traded Lapeer for Sanilac, Huron, and a small part of Macomb. Brown is a state rep (2006-2010, 2012-2014), but only represents 13% of the district.

26. [Van Buren, Allegan, Kentwood] Safe Republican.
(New district) McCain: 50.6, 2006 R Avg: 62.6 Romney: 54.8
Republican: Tonya Schuitmaker (incumbent)
Democrat: Jim Walters
Analysis: This new district replaces one eliminated from Wayne County. It contains Tonya’s home and all of her old state house district, but only about 10% of her current state senate district. Tonya is usually conservative and resides in Van Buren.

27. [Flint, central Genesee] Safe democrat.
Old SS 2010: 31-66, McCain: 23.6, 2006 R Avg: 31.6 Romney: 24.8
Democrat: Jim Ananich (incumbent)
Republican: Brendt Gerics
Analysis: The old district was vacated by John Gleason, who was elected Genesee County Clerk in 2012.

Republican: Dave Hildenbrand (incumbent)
Democrat: Penny Lance, Michael Scruggs
Analysis: Hildenbrand narrowly defeated Dave LaGrand in 2010 in the closest state senate race that year. The district drops Kentwood and adds several very conservative southwestern townships. It moved right 2.8/2.3%. Still, Grand Rapids has moved left over the past decade. Both democrats have lost previous races.

30. [Ottawa County] Safe Republican.
Old SS 2010: 76-21, McCain: 61.2, 2006 R Avg: 73.7 Romney: 66.8
Republican: Arlan Meekhof (incumbent)
Democrat: Sarah Howard
Analysis: Ottawa County is consistently the most Republican in Michigan. Meekhof is the favorite to be Senate majority leader next term.

31. [Bay, Tuscola, Lapeer] Likely Republican.
Old SS 2010: 59-41, McCain: 46.2, 2006 R Avg: 54.3 Romney: 51.4

It is unchanged by 2008 Pres and moves 0.3% left by 2006 avg, though Lapeer is less prone to large swings than the Thumb counties. Green is the strongest gun rights advocate in the state senate. He voted against Right to Work, likely for political reasons in this union-friendly district. He will face a primary against conservative state rep. Kevin Daley.

32. [Saginaw, W Genesee] Tossup.
Old SS 2010: 57-43, McCain: 42.4, 2006 R Avg: 50.7 Romney: 45.5

Democrat: Stacy Erwin Oakes, Garnet Lewis
Republican: Ken Horn
Analysis: Khan won a nail-biter 49-48.5 in 2006, and was re-elected more easily in 2010. This district drops Gratiot and adds Western Genesee, moving to the right 0.9/0.4%. Horn is a moderate who opposed Right to Work in this union-friendly district. Oakes, a black state rep (2010-2014) from Saginaw, will battle Lewis, a white progressive lesbian for the democrat nomination.

33. [Montcalm, Isabella, Gratiot, Mecosta, Clare] Safe Republican.
Old SS 2010: 65-32, McCain: 46, 2006 R Avg: 56.4 Romney: 50.9
Republican: Judy Emmons (incumbent)
Democrat: Fred Sprague

35. [NC Lower Peninsula] Safe Republican.
Old SS 2010: 63-34, McCain: 39, 2006 R Avg: 58.5 Romney: 53.9

Incumbent: John Moolenaar (running for Congress)
Republican: Jim Stamas
Democrat: Joe Lucasiewicz
Analysis: Moolenaar, who defeated Andy Neumann in 2010, is running for Congress. Midland punches above its weight politically, always having a state senator and congressman despite only having 42,000 residents. Stamas is a state rep (2008-2014) from Midland.

37. [NW Lower Peninsula, E Upper Peninsula] Safe Republican.
Old SS 2010: 65-35, McCain: 51, 2006 R Avg: 60.3 Romney: 56.2

The UP swings substantially depending on the year and the candidate. Casperson has voted a fairly moderate line in the state senate, in contrast to his conservative record in the state house.He opposed Right to Work, likely for political reasons, and switched his vote to support Medicaid expansion.
