Huh?
As a respected military hero and large landowner, he held local office and was elected to the Virginia provincial legislature, the House of Burgesses, beginning in 1758.
Washington opposed the 1765 Stamp Act, the first direct tax on the colonies, and began taking a leading role in the growing colonial resistance when protests against the Townshend Acts (enacted in 1767) became widespread. In May 1769, Washington introduced a proposal, drafted by his friend George Mason, calling for Virginia to boycott English goods until the Acts were repealed. Parliament repealed the Townshend Acts in 1770. However, Washington regarded the passage of the Intolerable Acts in 1774 as “an Invasion of our Rights and Privileges”.
In July 1774, he chaired the meeting at which the “Fairfax Resolves” were adopted, which called for the convening of a Continental Congress, among other things. In August, Washington attended the First Virginia Convention, where he was selected as a delegate to the First Continental Congress.

You are right. I forgot he was a member of the House of Burgesses. However there were several Presidents including Eisenhower who had held no previous elected office. My mistake was not double checking.
