so i did a little research
there are many uses of "varmint" before 2013 to literally describe undesirable animals, but no political references.
Jan 4, 2013: first use of "varmint" on PS (in recent years) as a possible descriptor of humans (not animals) --
Do you think any old time terms should come back to use?
here, fishface suggests bringing back the term "varmint" along with other words like "bandit" and "fancyman". presumably, he is referring to the use of the word to describe people, (perhaps referencing Yosemite Sam, although Sam was referring to Bugs Bunny -- who was not a human, but a human-like rabbit.) but even if his suggestion was to resurrect the word was for humans -- which is not clear-- it was not meant specifically for Trump supporters,obviously
April 5th, 2015:
Felix (strife) uses the term "varmint scrote" in a thread describing the DC Metro:
DC Metro Blows Infected Varmint Scrote
it's not exactly clear how varmint is being used here. "scrote" is "a worthless obnoxious person; a gobshite or toerag" (Wiktionary), or "a worthless fellow" (Dictionary.com). so it seems that "varmint" is being added to "infected" and "scrote" to heighten the level of disgust. within the OP, there is a link to a now-defunct video of a "guyess [with] a good rant about how much DC Metro sucks." so my guess is that the "infected varmint scrote" was the "guyess" with the rant about the Metro.
in which case this would be the first instance of "varmint" being used to describe a certain kind of person.

here, Felix uses "varmint" to describe a dog -- so, it doesnt count.

Total Reject pastes an excerpt from Hugh Glass: The Truth Behind the Revenant Legend: "Fitzgerald was the one who had convinced young Bridger to leave him–bear-battered but still breathing–at the Grand River. Where was that gutless varmint?" -- which would be an archaic use of term to describe a human

Felix (Ignominy) uses the term to describe the class in which Ted Nugent belongs:
"Terrible things are going to befall Nugent for not staying in the Varmint Lane."
i think this is key
ah, here we go --
February 17th, 2016:
Felix (Ignominy) uses the term "varmint" to describe a political demographic:
"pander to the mouthbreathing troglodyte varmint demographic, such as you and your sister-aunts and brother-uncles. Do I need to quote Mitch McConnell to you?"

Felix (Ignominy) calls Annotated a varmint:
oddly enough, the quote appears to have been subsequently deleted -- either by the mods or by Felix himself -- it shows up in the searchIgnominy wrote:Varmint, leave.Annotated wrote:I shit on your grave ... Obamastyle.

but NOT in the thread -- there is a gap at 5:25 PM, after Annotated's 5:18 post:
February 25, 2016:
Felix (Ignominy) uses the expression for the first time to describe the Trump voting class specifically:
"I like to call them Cletus or Critter or Varmint, but I'm not a Democrat"
Voting for Trump to piss off liberals
i think this is the first time this happens. henceforth, the term takes on a life of its own.
therefore, i think we can safely say Felix is indeed worthy of credit for originating the use of the term "varmint" to describe Trump supporters. worthy badge to carry.
