Jon Lieber, Managing Director of the United States for the Eurasia Group, shares his insights on the biggest development in the US election this week:

Joe Biden has chosen his running mate, Senator Kamala Harris of California. She was the safe pick, she was the betting market favorite, she brings diversity to the ticket and a historic component, as the first woman of color to ever run on a major party ticket in the United States. Most importantly, what she does is she doesn't open up any obvious lines of attack for President Donald Trump and she doesn't bring the risk of creating a competing power center on policy inside the White House, the way a progressive candidate might have.
