Anyone who spends a lot of time on the internet will know there’s a running joke that Ted Cruz is the Zodiac Killer.
The Zodiac Killer was responsible for a string of murders in California which began in the late 1960s, before Texas senator Cruz was even born.
But the joke, whose origins are somewhat murky, has been one of the internet’s favourite memes over the last three or four years.
And the Republican senator made the most of that fact with a Halloween tweet which featured a coded letter that was written by the killer back in the 1960s.
It’s not the first time Cruz has referenced the Zodiac Killer meme, but it did prove wildly popular, quickly racking up more than 100,000 likes.
The response, though, was very much mixed.
Some people loved that he was in on the joke.
Even some of those who support his opponent, Beto O’Rourke, in the forthcoming mid-term elections thought it was funny.
Some felt he was trying a little too hard.
And some felt that Ted Cruz being in on the “Ted Cruz is the Zodiac Killer” joke killed the “Ted Cruz is the Zodiac Killer” joke.
And some were outright hostile.
Others just filed it away as more evidence.
It’s not the first time Cruz has made a joke about “being” the Zodiac Killer – in fact it’s not even the first time he’s used that image to do it.
He tweeted the same picture around this time last year in a Twitter conversation with fellow senator Ben Sasse.
