Because I cannot seem to stop working with Ms. Dias, I roped her into writing the newsletter with me today. Our central idea: Abortion is like no other issue in American political life, planted at the intersection of health care, culture, science and morality. And, right now, abortion rights are under attack like never before.

Democrats say public opinion still sides with abortion rights. They cite recent electoral victories, big fund-raising numbers and the energy of “pussy hat”-wearing protesters. Yet, over the past year, state after state has passed new restrictions, making it harder to get an abortion in some places than at any point since Roe v. Wade legalized the procedure in 1973.

By many indications, the left is losing this fight. The advances of the right have been well documented. So our story focused on recent missteps and miscalculations made by abortion rights groups.

But most of the reaction to the story today centered not on the financial and cultural challenges within the movement, but on what everyone is focused on these days: 2020 politics.

On Twitter and in our inboxes, national abortion rights organizations argued that we had understated their political strength and popular support heading into a big election year.
