Send Cindy a physical postcard — printed on heavy cardstock and mailed by USPS to the Missouri State Capitol. State legislators hear from far fewer constituents than Congress does, so a single card carries real weight.

Capitol Mailing Address
State Senator Cindy O'Laughlin
Missouri State Capitol
Jefferson City, MO 65101
Mail to Missouri legislators is delivered to Missouri State Capitol in Jefferson City, where legislative staff log and route constituent correspondence. State capitols receive a fraction of the mail volume that Congress does, and unlike mail to Washington D.C. it is not irradiated — so a card addressed here arrives faster and competes with far less.
