The Missouri House Democratic Campaign Committee (MHDCC) is the campaign arm of the Missouri House Democratic Caucus. Our mission is to elect promising and passionate Democrat leaders across the state, in order to win back the Missouri House of Representatives one district at a time.


Sending Democrats to Jefferson City

Our priority is a simple one: elect Democrats. Right now we have a team of passionate leaders and candidates ready to stand up and fight for Missourians all across this state, but they cannot do it alone. However, with your help, we have the power to build grassroots campaigns and volunteer coalitions in every house district and put power back into the people's hands. We are the Missouri House Democrats, and we aim to restore transparency, accountability, and common sense reforms to Jefferson City.


In order to win seats, we have the important task of supporting candidates, coordinating volunteer actions and field programs, as well as amplifying the values and policies of our Democrat lawmakers in Jefferson City. Click through to find out more about our role throughout the state.


Part of our plan to win back Missouri is to provide crucial campaign support for each of our candidates. With our "Campaign-in-a-Box" package, Democrat candidates can access important tools for fundraising, building a volunteer field program, and messaging. Additionally, the MHD Team's role is to provide training, strategic counsel, and coordinate a volunteer field program with grassroots partners within each targeted House district.


The best way to support your local Democrats is to get engaged and volunteer at the local level. By signing up to volunteer through our website, we can connect you with local house candidates and party leaders, and make sure you are aware of upcoming events taking place in your area. Our statewide calendar gives you the opportunity to join your neighbors and local volunteers and take collective action in key races across the state.
