We inherited a mission—not a finished product.
The Preamble laid out the work: justice, peace, defense, shared well-being, liberty—for all.
The Constitution is the tool to pursue that mission.
But tools only matter if we know what they’re for—and are willing to use them.
That’s where we come in. Thinking isn’t extra—it’s the engine.
We do better when we think. That’s the deal.
