Defending Main Street Super PAC

The Defending Main Street (DMS) Super PAC is one of the nation’s most effective independent-expenditure organizations. The races we enter are in key, contested districts across the country that are crucial to securing a Republican majority in Congress. Once in office, our Members have been prolific, passing hundreds of fiscally responsible, socially inclusive bills through the House, the Senate, or both.


We defend key incumbent Republican seats and identify new candidates whom we can push to victory. In 2020, eight of the nine candidates we supported won, giving us an even better opportunity to be majority makers in the 2021-22 session. And we supported Randy Feenstra in the Iowa-04 primary against incumbent Steve King and in his subsequent victory in the general election.


More than 94 cents of every dollar raised goes directly to helping our candidates. We go into targeted districts, identify key voters, survey them, talk with them, and follow up by micro-targeting them online and through the mail. Our messaging reflects a deep understanding of the issues and values that each district’s voters are looking for.
