In which area does Texas have the least influence?

Texas has the least influence in controlling its border with Mexico due to the nature of federal jurisdiction and responsibilities regarding immigration and border security. While states have some role in managing certain aspects of their borders, the primary authority and regulation of immigration policies, border enforcement, and related matters fall under federal control. The federal government, mainly through agencies like Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE), oversees border security and immigration enforcement, which limits the state's ability to unilaterally shape policies in this area.

In contrast, Texas has significant influence over its taxation policies, law enforcement processes, and educational standards. These areas are primarily governed by state legislation and local regulations, allowing Texas to tailor its laws and systems to its specific needs and priorities. This means that while Texas can manage its fiscal policy, enforce laws, and set educational benchmarks, its capacity to influence border control is significantly restricted by the overarching framework of federal laws and regulations.
