It is plausible. Worse than that it fits all the evidence better than anything else.

Trump is not our "savior" as Jake Paul said and many faux Christians believe. The Deep State doesn't want him to be dead because they know how to kill people and this wasn't it. And no it wasn't a miracle of God to save the "anointed" Trump, because Trump is a lying sleazeball and not under such protection.

The "ear wound" was a stage job. A real rifle bullet would rip that ear in tatters. And Trump would be holding his ear and running, not getting his shoes and fist pumping the air.
