In 2010, Pridemore faced a three-way primary for the 99th District from Hartford Mayor Scott Henke and former Sussex Village Trustee Jim Batzko. With endorsements from the National Rifle Association and a 100% rating from Wisconsin Right to Life, Pridemore won with 58% of the vote.
2012 Primary
Redistricting moved Pridemore to the 22nd District. Hartford was no longer in his district, but most of Menomonee Falls and parts of Milwaukee were. In 2012, Nick Oliver challenged Pridemore for the Republican nomination for the 22nd Assembly District. With endorsements from the Menomonee Falls Taxpayer Association, Mark Belling, and Governor Scott Walker, Pridemore defeated Oliver 83% to 17%. Pridemore was unopposed in the general election after a review by the Wisconsin Government Accountability Board found that Democratic challenger Chad Bucholtz was 13 signatures short of the 200 needed to be on the ballot.
2014
On April 9, 2014, Pridemore announced that he was retiring from the Wisconsin Assembly.
Legislation
Healthcare whistleblowers
Pridemore has sponsored legislation to protect whistleblowers in the health care industry. His bill was supported by the Milwaukee Journal Sentinel.
Election reform
Pridemore has introduced legislation to require photo identification in Wisconsin elections. Special registration deputies would also be required to have a criminal background check. His bill would also move the party primaries from September to August so as not to conflict with a federal law intended to give military and overseas voters enough time to vote.
In 2012, Pridemore cosponsored a bill that recognized "nonmarital parenthood as a contributing factor to child abuse and neglect". He commented that in some situations there may be other options than divorce, stating "If they can refind those reasons and get back to why they got married in the first place it might help." Politifact rated as "True" the bill author's claim that children in a nonmarital parenthood setting "have a 20 times greater chance of being sexually abused."
Dog breeders
In 2011, Pridemore sponsored legislation that would redefine "commercial breeder" to protect hobby breeders and rescues from restrictions targeting large scale 'puppy mills.' The previous restrictions had been implemented by former Governor Jim Doyle in an effort to prevent 'puppy mills' where dogs live in abusive and neglectful conditions The Dog Federation of Wisconsin argued that the previous restrictions were negatively impacting "rescue groups and smaller humane societies". The previous restrictions were resulting in increased "dumping" of dogs in rural counties.
