Disappointee

An “appointee” is someone who a political committee selects to run for a political office. A person who tries, but fails, to be an “appointee” might be called a “non-appointee.”
 
In an October 30, 2009 interview, Republican strategist Karl Rove referred to a “non-appointee” as a “dis-appointee” (or “disappointee”). The term “disappointee” reflects the candidate’s “disappointment” at not being an “appointee.”
 
A “disappointee” can also mean an appointee who disappoints.

KARL ROVE: They had eleven Republican county chairs get together, eight candidates came to be interviewed, they settled upon a liberal Republican Assemblywoman and made her the endorsed Republican candidate and put her on the ballot. One of the other candidates—who was one of the “disappointees” if you will— a Saranac Lake candidate named Hoffman, tossed his hat in the ring on the Conservative party line.
