Cross-posted at The Western Right, Right Michigan, and RRH Elections.
All 38 seats in the Michigan Senate are up for election in 2014. Republicans currently have a 27-11 supermajority, and have controlled the senate since 1983. Republican control of the state senate has prevented democrats from complete control of Michigan's government in some years, and stopped a lot of bad things from being passed.
Fortunately for Republicans, the Michigan state senate is up only in midterms, which usually favor Republicans much more than presidential years. Republicans had a good year in 2014, picking up one state senate seat, following four pickups in 2010.
The 2010 redistricting produced a map that was moderately pro-Republican, while complying with all relevant laws.

Michigan Redistricting: Republican State Senate Map Passed
There are 26 open seats due to term-limits, 7 D and 19 R. All current state senators are former state representatives except three (Colbeck, Conyers, Hertel). This pattern held in the past, and most credible candidates this time are current or former state reps.
For the past few years, the state senate has been more moderate than the state house. This cycle, several ideologically split Republican primaries resulted in a state senate that will be slightly more conservative than before.
I have included election data for the 2014 state senate election, and McCain (2008), Romney (2012), and Trump (2016) results in each district. More data is available from Republican Michigander and RRH Elections.
