The California Senate is the upper house of the California State Legislature, responsible for making state laws. It consists of 40 members, each representing a specific district within the state. Senators serve four-year terms, with a limit of two terms in office. The Senate works alongside the California Assembly, the lower house, to draft, debate, and vote on legislation. Key responsibilities include approving the state budget, confirming appointments made by the Governor of California, and addressing issues such as education, healthcare, and public safety.
