Jon Lieber, head of Eurasia Group's coverage of political and policy developments in Washington, shares his perspective on US politics:

What will be the immediate impact of the Supreme Court's decision to overturn Roe v. Wade?

This week's decision is the culmination of 40 years of work by the conservative legal movement to create the alignment of justices willing to make this choice, which ironically came together during the presidency of Donald Trump, who, for most of his career, was not a conservative Republican. Abortion could become a relevant issue in the midterm elections, but surveys are showing that most voters are much more activated by the economy at the moment than abortion. That could change however as there's going to be a movement in states to either deny or preserve access to abortion, which could put the issue on the ballot in places like Pennsylvania, Michigan, Arizona and Georgia.
