It's even worse than that
If you were chatting with them and you used the proper name "Affordable Care Act" or ACA to describe Obamacare they would immediately think it is a dog whistle for communism and that it was just a way for liberals to rebrand Obamacare. Their entire universe is backwards, inside out, and upside down.
See that's just it I don't think this picture shows that he was stupid as a kid I think it shows that he's unwilling to grant the freedom of self-expression and self-discovery that he went through to kids today.
It's not his participation in this picture that is damning in any way, It's who he is now that damns him.
The kid in this picture was doing normal kid shit, I can't even figure out why someone might be offended by it but I know a Republican WOULD immediately reach for their pearlsif they saw this picture thinking it was taken recently. They would call it wokeness, and attribute it to the deep state.
