Kamala Harris’s endorsement of Joe Biden served a very specific purpose: She wants a prominent role in his administration.

Some have speculated Harris is vying for Biden’s vice president pick, but confidants of Biden are privately discussing the possibility of making Harris attorney general. This would be a disastrous decision on Biden’s part. One of the reasons Harris’s presidential campaign failed was that she couldn’t reconcile her progressive posture with her past as a criminal justice hardliner. The California senator’s record as a prosecutor was and still is problematic to most Democratic voters, and Biden’s vote of confidence is unlikely to change that.
