I'm just worried that even if Hillary is reelected in 2020, her coattails won't be large enough to give Dems control of enough state legislatures (redistricting power).
Kennedy & Ginmsburg will be replaced in 2020, anyways and Lorretta Lynch if she replaces Kennedy, being former attorney general will strike down the GOP gerrymandering that Roberts and Alito created. If Charlie Crist is elected GOV in FL, and Dems win NV, CO, FL, MI, MD, ME, IL & NM govs, it will be enough.
Lynch isn't getting appointed to the SCOTUS. She's not held in high regard by the party base. If a Democratic President wants to appoint a former AG then Holder is the obvious choice.
