What is required for the General Assembly to override a governor's veto?

For the General Assembly to successfully override a governor's veto in Missouri, it requires a two-thirds vote in both the House of Representatives and the Senate. This supermajority requirement is significant because it establishes a higher threshold that must be met, reflecting the serious nature of overriding a governor's decision. The rationale behind this requirement is to ensure that there is substantial legislative consensus before overriding the executive's veto, thus maintaining a system of checks and balances within the state's government.

This process is a vital part of the legislative framework, allowing the General Assembly to assert its authority and reflect the will of the citizens in cases where the governor may not align with legislative priorities. The need for two-thirds in both chambers emphasizes the need for agreement across the political spectrum, suggesting that a simple majority may not sufficiently represent the will of the populace.

The other options do not provide the correct framework for override, as a majority vote would not reflect enough agreement to counteract the veto effectively, a simple majority in the Senate would still leave the House's decision vulnerable, and a unanimous vote is not a feasible requirement for legislative action.
