Actually people wearing buttons and putting up Cthulhu posters is ancient, it's been done for decades now. Sort of like the old "thought police" jokes and alleged organizations like "Students for an Orwellian Future".
This is why I say "no" it's just too trite and overdone.
The original joke was a slogan on posters and buttons saying "Cthulhu for President! Why vote for the lesser of two evils?". During BOTH elections before Obama there was also a "Bushthulhu" campaign joke being run off the Palladium boards by left wingers which was basically a satire of the now-ancient Cthulhu for president satire.
Truthfully I've always wanted to promote Warren Ellis' version of a left wing cantidate: "The Smiler", as a joke cantidate. Alas there aren't enough people interested in that one to actually spread it around.
The point being in his "Transmetropolitan" books that Spider goes to town on the current president he calls "The Beast" who is a huge right winger and has even done things like condemn segements of the population to toxic housing. Of course Spider is all over the guy, and criticisms of him make him famous. However in the end after doing his part to destroy the guy's campaign he realizes he was wrong, and a totally insane left winger comes into power with exagerrated policies based on real world leftist issues "to protect us from outdated and dangerous language and concepts in the costitution, like free speech". One of the reasons why I give Ellis so many points as a writer, he's a leftist IRL but slammed both sides more or less equally. Besides the final speech by The Beast to "Spider" that makes Spider realize how bad he F@cked up in that story kind of stuck in my mind "Don't say I don't believe in anything. I don't believe in anything YOU agree with, but that's not the same thing" and pointing out that with such a F@cked up world if he even makes 51% of the population happy and better off than they would be without him, in the end it's a win. Totally psycho guy too, but it was a powerful point taken in the context of a very disturbing portrayal of the future.
