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

Capitol Mailing Address
State Representative Jon Cardin
Maryland State House
Annapolis, MD 21401
Mail to Maryland legislators is delivered to Maryland State House in Annapolis, 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.
