Senator George McGovern once said, “The highest patriotism is not a blind acceptance of official policy, but a love of one's country deep enough to call her to a higher plain.” Senator McGovern’s vision emboldened Democrats decades ago, and it continues to empower Democrats today. The mission of the South Dakota Democratic Party is to build and sustain a healthy political process in South Dakota by electing Democrats to all levels of office. We Are Democrats Working Together. Winning for South Dakota.
