There is SOME plausable deniability, in a strict legal sense, because neither 86 nor 47 are overt and literal references.
However, Almost every knows what that means.
These are not obscure references.
I bet if you polled 100 random people AT LEAST 50% would be able to deduce the connotation.
What is more, if this had been done about Biden or Obama, the media would be in a flippin’ frenzy!
