On the Kirk being murdered by the far right (you did on here of course), but of the notable left wing media figures:
Jimmy Kimmel:
On his show, framed MAGA efforts to characterize the shooter as non-left as scoring points, implying the killer fit as “one of them.”
Vox
Keith Edwards (former Democratic operative, large YouTube channel): Claimed it looked “more and more like… far right… Maybe what is called a Groyper.”
Spiked-online
Keith Olbermann: Called Robinson an “ultra-right gun-nut Republican-raised Groyper monster” and repeated the framing.
Malcolm Nance, Benjamin Dixon, actor Billy Baldwin,
Mother Jones editor Clara Jeffery, Atlantic contributor Norm Ornstein, Occupy Democrats, and various left-leaning influencers/streamers: Promoted or amplified Groyper/far-right framing based on memes, family background, or early incomplete reports, even as contrary evidence mounted.
As for the 'Trump assassation attempt was staged', (Wisbech Eagle did that one on here).
Leigh McGowan (PoliticsGirl): Explicitly stated in a widely viewed TikTok that the Butler attempt “was not a real assassination attempt.” She has a large following and has partnered with Democratic entities.
Jennifer Welch and Angie Sullivan (“I’ve Had It” podcast): Agreed on air that Trump staged the Butler attempt, citing elements like the flag, press positioning, and the iconic fist photo.
Dmitri Mehlhorn (Democratic donor adviser linked to Reid Hoffman): In an email, urged considering the possibility the “shooting” was encouraged or staged for photos and backlash benefit.
Amanda Seales and accounts such as @LakotaMan1: Called it staged theater or suggested Trump “sacrificed” a supporter for realism.
Not sure why I'm meant to rank blue anon theories next to right wing theories.
On the aspect of how popular a theory is on the right compared to the left.....Does anyone actually know the answer to that unless there is polling data. Also, shouldn't a theory actually be something I believe to be true to bother commenting on it....You commented on the 'Kirk was murdered by a Groyper' theory because you believed it.....why am I meant to rank theories that I'm not interested in.
If you want me to answer this question you need to be specific about which theory (as I was).
