In the episode “Falling,” Supergirl’s Cat Grant (Calista Flockhart) needs a replacement for Lucy Lane, who resigned from CatCo during last week’s show. When Kara (Melissa Benoist) tells her she has a list of qualified applicants who are ranked according to the “least annoying,” Cat asked if there were any Republicans. Kara answers, yes – but they're reformed. Cat, a Hillary supporter, is happy with that answer.
Cat: So, I demanded a list of replacements for Lucy Lane, like, yesterday.
Siobhan: Ms. Grant...
Kara: Ah, here you are. I already checked all their references and ranked them according to who you'll find the least annoying.
Kat: Oh, any Republicans?
Kara: Two reformed.
Got it. Only reformed Republicans need apply.
A brief enough reference to Republicans as the undesirables but it was gratuitous. Most of all it was unnecessary.
