What would it take to end child marriage? There’s a new federal push to limit it.

Missouri voters will determine the outcome of four statewide constitutional amendments during the August 2026 primary election. Among these measures is Amendment 5, which aims to gradually eliminate the state's income tax. Additionally, Amendment 4 proposes specific changes to the existing citizen-led initiative petition voting process. Separately, there is a new federal push focused on limiting child marriage. These developments highlight significant legislative and constitutional shifts occurring within the state of Missouri and at the federal level.
