What fraction of both houses is required to override a governor's veto?

• A. Two-thirds.
• B. Three-fifths.
• C. A simple majority.
• D. Unanimous vote.

Answer: (A)

Overriding a governor's veto is a legislative check on executive power. In Wyoming, it requires a two-thirds vote of all members in each house. That means each chamber must pass the bill again with two-thirds of its total membership, not just among those who vote. For example, with a 60-member House you’d need 40 votes; with a 30-member Senate you’d need 20 votes. If either chamber falls short, the veto stands.

This higher threshold is designed to require broad, cross-party support for important legislation, rather than a simple majority. The other fractions aren’t the standard for veto overrides: a simple majority is too easy, a three-fifths isn’t the established rule in Wyoming, and a unanimous vote is far more stringent than the constitutional requirement.
