Frasier and Niles disapprove of Martin endorsing a right-wing political candidate.
Upset that Martin is actively endorsing (and appearing in a commercial for) a right-wing congressional candidate, Frasier decides to get behind his opponent, but becomes conflicted about it when his candidate reveals something personal to him.
When the congressional candidate whom Martin supports demeans Frasier on air, he decides to publicly support the man's opponent, but he re-evaluates his decision when the latter confides a secret that causes Frasier to question his competency to run for public office.
