Which movement has had the largest impact on state legislative races in recent years?

The Democratic Party's focus on state-level races, particularly in the wake of the 2010 census and subsequent gerrymandering, has had a significant impact on state legislative contests in recent years. This movement, often referred to as the "Blue Wave," has been driven by grassroots organizing, increased funding from national organizations, and a concerted effort to target swing districts. Additionally, social movements advocating for issues like healthcare, education, and voting rights have mobilized voters and influenced legislative agendas, further shaping the outcomes of these races.
