That site is a political advocacy org for a certain brand of economic liberalism. At least they're pretty open about it:

> The Argument is a mission‑driven media company based in Washington, D.C. We make a positive, combative case for liberalism through sharp, well-argued opinion pieces, original reporting, and multimedia content that confronts the illiberal drift in our politics.

We aim to persuade, not preach; argue, not just diagnose. Our coverage will focus on the politics and economics of growth, technology and society, gender and family.
