Congressional Democrats — in both chambers of Capitol Hill’s legislative body — now have a chance to make good on where congressional Republicans have face-planted.

The GOP wanted to replace the Affordable Care Act. They wanted first to repeal the law, then substitute something else in its place. They just couldn’t cobble together a law that pleased everyone within their caucus, let alone the rest of this vast country.

They have cratered. Their repeal and replace effort is done. Gone. Kaput. Toast.

What’s left? Oh, wait! They can work with congressional Democrats. They can figure out a way to make changes to the ACA, if only congressional Republicans can stomach the idea of maintaining something with Barack H. Obama’s name on it.

In order, though, for Republicans to reach across the aisle, their legislative colleagues — Democrats, I must add — need to offer a starting point.

Suppose it comes to a repair and revamp effort on the ACA, what might the Democrats offer as their chief sticking point?

Are premiums too high? Do Americans have enough choices of doctors? Are there ways to actually make the ACA more, um, affordable for every American who applies for insurance under the government plan?

Democrats have said they are willing to work with Republicans to improve the ACA. To get the discussion started, though, we need to hear from Democratic political leadership on where they intend to start.

We’ve hearing a lot of yapping and yammering from Republicans — for too long, if you were to ask my opinion. Now it’s time for Democrats to take the stage.
