In an earlier post you wanted to ban a song that reached #1 on the charts. I'm not clear on exactly who should do the "ranking".
I don't support "banning" anything, and have never used the word "ban" in reference to a song. As for who should do the ranking, whoever owns the transmitter and associated studio equipment ultimately makes the decisions on what does or doesn't get played. The owner may delegate that authority to employees, which is his right and privilege. Any and all such decisions, whether it is ranking songs from best to worst, or simply using a pass-fail grading system, are for the owner of the station to make.
However, if the owner of the station wants to attract listeners to his station, so that he has an optimal size audience to rent to advertisers to generate revenue, then that owner will include what those listeners want to hear as a factor in making his decisions. If he's smart, he'll gather information from a variety of sources and will also use his own intuition and experience. If he's lazy, he'll hire some consultant to do the work for him, and to take the blame if it fails.
As for chart positions for a novelty song decades ago, that's also another factor to consider, albeit a minor one. It is especially trivial when talking about a flash-in-the-pan one-hit-wonder.
I agree with you on that, but even if Sen. Kennedy had lived to a ripe old age, you wouldn't be hearing that one now, because it would be largely irrelevant now, which I am guessing also applies to the Dirksen parody, which I don't recall ever hearing. Apparently, Minkin at least learned from Vaughn Meador's mistakes, and didn't "put all his eggs in one basket."
The "Wild Thing" RFK parody, and "Mr. Custer" by Larry Verne were two songs that I specifically mentioned in a thread of mine to which I gave the subject line, "politically incorrect songs." I had never heard either of these, but I became aware of "Mr. Custer" after reading about it in The Billboard Book of #1 Hits and wanted to hear it. Once youtube came along, I googled it and took a listen. It is crap, but still worth taking a listen to in your spare time. (I was not old enough to remember either of these, which explains why I had never heard them.)
I remember "Mr. Custer" very well from first-hand listening. It was a cute little novelty song, no better or worse than other such songs like "Runnin' Bear". But it's extremely dated. Likewise, the "Wild Thing" RFK parody would have had about the same shelf life as any of Weird Al Yankovic's parodies. They're funny at the time, but they aren't destined for long lives.
However, though they aren't worth replaying today because as novelty songs they just aren't funny anymore, they are not "politically incorrect". It is one of my biggest wishes that the phrase (and concept of) "political correctness" would disappear totally from American culture, once and for all.
