With the bill’s text still not released for public view, Vox asked GOP senators to explain their hopes for it. Who will benefit from the legislation? What problems is this bill trying to solve?

“All of them,” Sen. John McCain said in an interview, not an uncharacteristic response of his Republican Senate colleagues.

Over the course of the past week, Vox asked eight different Republican senators to explain the affirmative case for the bill. They rarely answered directly, at least not on the bill’s policy merits.

Sometimes, a senator could identify a desired outcome, like “lowering premiums” or “stabilizing marketplaces.” But they rarely could explain the mechanism through which they planned on achieving that outcome.
