In 2016, Obernolte introduced Assembly Bill 2341, which would provide San Bernardino and other rural counties with additional judges to resolve backlogged court systems.[16] The bill would have shifted seats from Santa Clara and Alameda counties to the rural counties including San Bernardino, but died in the Senate Appropriations Committee without a hearing.[17][18]
Obernolte said that Governor Jerry Brown's $179.45 billion budget proposal was "responsible", but expressed a preference for fixing existing programs over creating new ones. He also stated an interest in funding job skills training, improving the state's Denti-Cal program, repairing infrastructure, and working on the housing crisis. Obernolte pushed for lawmakers to limit long-term funding commitments and said the budget proposal did nothing to address the "state's out-of-control pension debts and retiree health care liabilities."[20]

Obernolte promotes accountability by local businesses to fairly compete with newer ones, therefore a wage should be determined by the business, especially small or family businesses which have been unable to compete in California due to over-regulation. He also believes in diverse skill acquisition which leads to higher wages, for example among teenagers that may benefit from working, without competing with older people for higher 'living' wages. Skill acquisition may help the decline in nationwide volunteering.[27]

The taskforce was established "to explore how Congress can ensure America continues to lead the world in AI innovation while considering guardrails that may be appropriate to safeguard the nation against current and emerging threats".[53][54]

On July 19, 2022, Obernolte and 46 other Republican representatives voted for the Respect for Marriage Act, which would codify the right to same-sex marriage in federal law.[59] He said, "As an ardent advocate for limited government, I do not feel that government should be empowered to dictate the terms of a marriage."[60]
