The last time someone on death row was executed was in the last century.

If a Senator resigns, dies, or is removed, the Governor appoints someone to finish their term. Here, this idea is largely stemming from a custom that is sometimes followed, mostly when a Senator dies: Sometimes a Governor will appoint the Senator’s spouse to continue their “legacy.” The decision is up to the Governor, however, and anyone who is Constitutionally permitted to serve in the United States Senate is allowed to be appointed.
