How are Senate elections structured in Texas?

In Texas, the structure of Senate elections is designed so that half of the senators are elected every two years. This system is known as staggered terms, which allows for continuity within the Senate while still providing an opportunity for new members to be elected regularly. Each senator serves a four-year term, but only half of the Senate is up for election during any given election cycle. This means that every two years, voters in Texas can elect senators, but they will only be deciding on half of the Senate, maintaining a balance and stability in legislative operations.

The other choices reflect misunderstandings of how the Texas Senate functions. While it is true that Senate elections involve a popular vote, the phrase "decided by popular vote" does not capture the structured staggered election process. Furthermore, the concept of all senators being up for election every two years would lead to a complete turnover that could destabilize the legislative process, and it is simply not how the Texas Senate is organized. Therefore, the chosen answer accurately represents the unique electoral system of the Texas Senate.
