At that time a voting age of 16 was proposed by the Green Party, but was not adopted. The voting age for municipal elections in some states was lowered to 16 in the early years of the 2000s. Three states had made the reduction by 2003 (Burgenland, Carinthia and Styria), and in May 2003 Vienna became the fourth.he 26th Amendment to the U.S. Constitution prevents states from denying suffrage to 18-year-olds, but does not prevent states from establishing a lower voting age. Several states (Georgia, Kentucky) already allowed 18 year olds to vote prior to passage of the 26th amendment.
