The most helpful evidence in developing a fair and effective counterclaim would be:
As the capital of the United States, Washington, DC was never meant to be a state because the founding fathers feared its people would have too much influence.
This evidence directly addresses the argument for DC statehood by suggesting a foundational intent regarding its status as the nation's capital and the potential implications of statehood on political influence, thereby providing a clear counterpoint to the argument for representation and equality.
