The primary election took place on September 14, 2010.

District 3
Incumbent Democrat Tim Carpenter ran for re-election.
District 5
Incumbent Democrat Jim Sullivan ran for re-election. He faced Republican state representative Leah Vukmir in what was described as the most vulnerable seat for Democrats that cycle. Going into the election, the 5th district was rated as a tossup, with Vukmir outraising Sullivan in the first six months of the campaign and outside campaign spending flooding into the district.[9] Due to outside spending, the 5th district proved to be the most expensive race in the chamber.[10] During the campaign, Sullivan made attempts to distance himself from incumbent governor Jim Doyle, who saw his poll numbers collapsing going into the election year.[11] While Democratic strategists viewed any competitive margin from Sullivan as a sign of a well fought campaign, arguing that Vukmir was too extreme for the moderately conservative suburban district.[12] Vukmir defeated Sullivan by a five-point margin.
| Party | Candidate | Votes | % | |
|---|---|---|---|---|
| Republican | Leah Vukmir | 36,852 | 52.15 | |

District 7
Incumbent Democrat Jeffrey Plale ran for re-election. He faced Democratic county supervisor Chris Larson in the primary election. In previous cycles, Plale had faced challengers from the left in 2003 and 2006, both of whom he had defeated soundly.[13] Going into the 2010 cycle, however, Plale faced a stronger challenger in Milwaukee County board member Chris Larson. During the campaign, Plale faced criticism for his stances as a conservative Democrat, as well as blocking a key environmental bill he had previously supported.[14] Due to his part in killing the climate bill, Plale lost the support of governor Jim Doyle, who had supported the legislation.[15] Despite this loss of support, Plale still had the support of majority leader Russ Decker, himself locked in a close re-election, and endorsements from state representatives Christine Sinicki and Jon Richards as well as WEAC.[16] The campaign also took on a regional tone, as Plale's base was in Cudahy, St. Francis, and South Milwaukee, while Larson's base centered around the south and east sides of Milwaukee.[14] Seeking to defeat Plale, progressives had hoped the competitive Republican gubernatorial primary would sap away conservative Democrats who would have otherwise voted for Plale.[14] Larson defeated Plale in an upset, winning by a 21-point margin.[17] Larson went on to defeat Republican Jess Ripp by a 15-point margin.
| Party | Candidate | Votes | % | |

District 21
Incumbent Democrat John Lehman ran for re-election. Two Republicans announced campaigns to face the Racine Democrat, being county board member Van H. Wanggaard and Bob Gulan, in what was projected to be a tight race for Lehman. Lehman had been initially elected in 2006 amid a national backlash to the administration of George W. Bush. Lehman was predicted to face a tough re-election, due to the faltering economy in Racine, as well as an unenergized base and energized opposition. Due to these circumstances, the district was seen as a tossup, with some political commentators viewing the seat as most likely to flip into the Republican column.[18] Wanggaard defeated Lehman by a five-point margin.
| Party | Candidate | Votes | % | |
|---|---|---|---|---|
| Republican | Van H. Wanggaard | 13,864 | 79.89 | |

District 23
Incumbent Democrat Pat Kreitlow ran for re-election. He was defeated by former Republican state representative Terry Moulton by an eight-point margin.
District 25
Incumbent Democrat Robert Jauch ran for re-election. He defeated Republican business owner Dane Deutsch by a three-point margin. During the campaign, Deutsch sparked controversy due to social media posts he made where he compared Adolf Hitler and Abraham Lincoln, calling both strong leaders.[19]
District 27
Incumbent Democrat Jon Erpenbach ran for re-election. Three Republicans filed for the nomination, Kurt Schlicht, home-builder Tom Lamberson, and Tony Wickersham. Schlicht won the primary by a wide margin and faced Erpenbach in the general election. He was defeated by a wide margin.
District 29

Incumbent Democrat Russ Decker ran for re-election. In what was initially viewed as a longshot bid, two Republicans business owner Pam Galloway and 2006 nominee Jimmy Boy Edming ran for the nomination. Galloway won the nomination by a wide margin and went on to face Decker. Initially deemed a safe seat for Decker, he was eventually locked in a tight race with Galloway, which attracted high amounts of outside spending.[20] Decker was defeated by Galloway by a five-point margin.
| Party | Candidate | Votes | % | |

| Republican | Pam Galloway | 10,351 | 70.45 | |

District 31
Incumbent Democrat Kathleen Vinehout ran for re-election. She faced former Tomah mayor and 2002 Libertarian nominee for governor Ed Thompson. In September, Thompson was diagnosed with cancer, which hindered his ability to campaign.[21] Throughout the campaign, some Republican strategists feared that Thompson's Libertarian views could frustrate the Republican goal of a senate majority, and that if he were elected, he could serve as a de facto majority leader in the state senate.[22] The district was, however, seen as a long-shot for Republicans, and was rated by WisPolitics as "lean Democratic", with his eccentric political beliefs and familial ties to former governor Tommy Thompson providing a mixed image of his electability in the district.[12]
| Party | Candidate | Votes | % | |
|---|---|---|---|---|
| Democratic | Kathleen Vinehout (incumbent) | 30,314 | 50.27 | |
| Republican | Ed Thompson | 29,911 | 49.61 | |
| Write-in | 73 | 0.12 | ||
| Total votes | 60,298 | 100.0 | ||
District 33
Incumbent Republican Theodore Kanavas declined to seek re-election. Republican Rich Zipperer defeated candidate Tim Dietrich by a wide margin. In the general election, Zipperer was elected unopposed.
