How strong is this Blue Wall and what exactly is it? This metaphor labels traditional blue states with high union-density that deliver the necessary electoral college votes for the Democratic Presidential candidate. In 2016, this wall came crashing down. Turning their backs on Clinton and against the direct wishes of their union leadership, union voters gave the nation four tumultuous years of Trump. In 2020, these union voters in Wisconsin, Michigan and Pennsylvania sobered up and pulled the lever for Biden. Nevertheless, in red-state Ohio, union voters are still drunk on Trump.
