Arizona Governor Doug Ducey recently appointed Martha McSally, the losing candidate in the 2018 Senate election, to the state's other Senate seat.
Is there any precedent since 19131 for a Senate candidate who lost, to be appointed to the Senate shortly2 after the election?
1The Seventeenth Amendment to the United States Constitution was ratified which established the direct election of senators, as well as means of filling vacant Senate seats.
2For this question, I've defined "shortly" as "a period of two years since the previous election", i.e. if the candidate lost in the 2018 Senate election, "shortly" refers to the period between 2018 to 2020.
