Already, because of the Affordable Care Act, more than 3 million Americans under age 26 have gained coverage under their parents' plans.

More than 9 million Americans have signed up for private health insurance or Medicaid coverage.

And here's another number: zero. Because of this law, no American can ever again be dropped or denied coverage for a pre-existing condition like asthma, back pain, or cancer. No woman can ever be charged more just because she's a woman. And we did all this while adding years to Medicare's finances, keeping Medicare premiums flat, and lowering prescription costs for millions of seniors.

Now, I don't expect to convince my Republican friends on the merits of this law. But I know that the American people aren't interested in refighting old battles. So again, if you have specific plans to cut costs, cover more people, and increase choice - tell America what you'd do differently. Let's see if the numbers add up. But let's not have another forty-something votes to repeal a law that's already helping millions of Americans like Amanda. The first 40 were plenty. We got it. We all owe it to the American people to say what we're for, not just what we're against.
